    No. 5A14
    Filed 19 December 2014
    STATE OF NORTH CAROLINA
    v.
    GLENN EDWARD BENTERS
    Appeal pursuant to N.C.G.S. § 7A-30(2) from the decision of a divided panel
    of the Court of Appeals, ___ N.C. App. ___, 
    750 S.E.2d 584
    (2013), affirming an
    order granting defendant’s motion to suppress entered on 24 September 2012 by
    Judge Carl R. Fox in Superior Court, Vance County. Heard in the Supreme Court
    on 8 September 2014.
    Roy Cooper, Attorney General, by Derrick C. Mertz, Assistant Attorney
    General, for the State-appellant.
    Brock & Meece, P.A., by C. Scott Holmes, for defendant-appellee.
    BEASLEY, Justice.
    In this appeal we consider the sufficiency of an affidavit in support of an
    application for a search warrant.       We hold that under the totality of the
    circumstances, the affidavit failed to provide a substantial basis for the magistrate
    to conclude that probable cause existed.        The information available to law
    enforcement officers from an anonymous tip and from the officers’ corroborative
    investigation was qualitatively and quantitatively deficient, and the affidavit’s
    STATE V. BENTERS
    Opinion of the Court
    material allegations were uniformly conclusory. Accordingly, we affirm the Court of
    Appeals.
    The affidavit at issue provides in relevant part as follows:
    I, Deputy Joseph R. Ferguson, am a certified North
    Carolina law enforcement officer, sworn and employed by
    the Vance County Sheriff’s Office. I have been a sworn
    law enforcement officer since 1998. While employed by
    the Sheriff’s Office I have been assigned to the patrol
    division, the Community Policing Program, and am
    currently a Detective Lieutenant in the Criminal
    Investigations and Narcotics Division. I have attended
    and successfully completed Basic Law Enforcement
    Training and obtained an Associates Degree in Applied
    Science in Criminal Justice Technology at Vance
    Granville Community College.         I have received the
    following training related to the enforcement of North
    Carolina State Laws: Constitutional Law, Arrest, Search,
    and, Seizure, Search and Seizure in North Carolina,
    Criminal Investigations, Search Warrant Preparation,
    Interview     and     Interrogation,    Advance      Death
    Investigations, and Crime Scene Processing as part of the
    in service training courses provided by the          North
    Carolina Community College system[.]           I have also
    completed the Drug Law Enforcement Training Program
    through the Federal Law Enforcement Training Center
    and attended the Discovery for Law Enforcement Agents
    Seminar sponsored by the Eastern District of North
    Carolina’s U.S. Attorney’s Office. During my career in
    law enforcement I have investigated over one thousand
    criminal cases and have made over five hundred arrests
    many resulting in conviction by trail [sic] or plea bargain
    in Vance County District and Superior Courts.
    On September 29, 2011 Lt. Ferguson, hereby
    known as your affiant, received information from
    Detective J. Hastings of the Franklin County Sheriff’s
    Office Narcotics Division about a residence in Vance
    County that is currently being used as an indoor
    -2-
    STATE V. BENTERS
    Opinion of the Court
    marijuana growing operation. Detective Hastings has
    extensive training and experience with indoor marijuana
    growing investigations on the state and federal level.
    Within the past week Hastings met with a confidential
    and reliable source of information that told him an indoor
    marijuana growing operation was located at 527 Currin
    Road in Henderson, North Carolina. The informant said
    that the growing operation was housed in the main house
    and other buildings on the property. The informant also
    knew that the owner of the property was a white male by
    the name of Glenn Benters. Benters is not currently
    living at the residence, however [he] is using it to house
    an indoor marijuana growing operation. Benters and the
    Currin Road property [are] also known by your affiant
    from a criminal case involving a stolen flatbed trailer with
    a load of wood that was taken from Burlington North
    Carolina. Detective Hastings obtained a subpoena for
    current subscriber information. Kilowatt usage, account
    notes, and billing information for the past twenty-four
    months in association with the 527 Currin Road
    Henderson NC property from Progress Energy Legal
    Department. Information provided in said subpoena
    indicated that Glenn Benters is the current subscriber
    and the kilowatt usage hours are indicative of a
    marijuana grow operation based on the extreme high and
    low kilowatt usage.
    Also on 9-29-2011 Detective Hastings and your
    affiant along with narcotics detectives from the Vance and
    Franklin County Sheriffs’ Office as well as special agents
    with the North Carolina S.B.I. traveled to the residence at
    527 Currin Road Henderson NC[ ]and observed from
    outside of the curtilage multiple items in plain view that
    were indicative of an indoor marijuana growing operation.
    The items mentioned above are as followed [sic]; potting
    soil, starting fertilizer, seed starting trays, plastic cups,
    metal storage racks, and portable pump type sprayers.
    Detectives did not observe any gardens or potted plants
    located around the residence. Detectives observed a red
    Dodge full size pickup truck parked by a building located
    on the curtilage of the residence and heard music coming
    -3-
    STATE V. BENTERS
    Opinion of the Court
    from the area of the residence.
    After observing the above listed circumstances,
    detectives attempted to conduct a knock and talk
    interview with anyone present at the residence. After
    knocking on the back door, which your affiant knows
    Benters commonly uses based on previous encounters,
    your affiant waited a few minutes for someone to come to
    the door. When no one came to the door, your affiant
    walked to a building behind the residence that music was
    coming from in an attempt to find someone. Upon
    reaching the rear door of the building, your affiant
    instantly noticed the strong odor of marijuana emanating
    from the building. Your affiant walked over to a set of
    double doors on the other side of the building and
    observed two locked double doors that had been covered
    from the inside of the building with thick mil black plastic
    commonly used in marijuana grows to hide light
    emanated by halogen light typically used in indoor
    marijuana growing operations. Thick mil plastic was also
    present on windows inside the residence as well.
    Based on these facts your affiant respectfully
    request[s] a search warrant in order to obtain evidence
    from the property located at 527 Currin Road Henderson
    NC . . . .

    Date                       Date
    That same day, a magistrate issued a warrant based upon this affidavit
    authorizing a search of defendant’s home and outbuildings on his property. Law
    enforcement officers immediately executed the warrant and seized fifty-five
    -4-
    STATE V. BENTERS
    Opinion of the Court
    marijuana plants; various indoor growing supplies, including lights, timers,
    chemicals, water pumps, flexible tubing, humidifiers, and several boxes of Ziploc
    plastic bags; numerous firearms and ammunition; and $1540 in cash.
    A grand jury indicted defendant for maintaining a dwelling to keep a
    controlled substance (two counts), manufacture of a Schedule VI controlled
    substance, possession of drug paraphernalia, trafficking in marijuana by
    manufacture, trafficking in marijuana by possession, and possession with intent to
    sell or deliver a Schedule VI controlled substance. On 20 February 2012, defendant
    moved to suppress the items seized under the search warrant, arguing that the
    search and seizure violated the Fourth Amendment to the United States
    Constitution and Article I, Section 20 of the North Carolina Constitution. On 24
    September 2012, the trial court entered an order allowing defendant’s motion. The
    State timely appealed to the Court of Appeals.
    A majority of the panel of the Court of Appeals concluded that the affidavit at
    issue was not supported by probable cause and affirmed the trial court’s order
    allowing defendant’s motion to suppress. State v. Benters, ___ N.C. App. ___, ___,
    
    750 S.E.2d 584
    , 591 (2013). The dissent agreed with the majority “that the affidavit
    did not contain a sufficient factual basis to establish probable cause under the
    confidential informant standard” because “L[ieutenant] Ferguson’s description of
    the source’s reliability was merely conclusory.” Id. at ___, 750 S.E.2d at 591-92
    (Hunter, Robert C., J., dissenting). The dissent, however, would have concluded
    -5-
    STATE V. BENTERS
    Opinion of the Court
    that the affidavit was supported by probable cause under an anonymous tip
    standard because “the affidavit contained detailed information provided by the
    source which was independently corroborated by experienced officers.” Id. at ___,
    750 S.E.2d at 591. The State appeals to this Court based on the dissent. N.C.G.S. §
    7A-30(2) (2013). We now affirm.
    The issue before this Court is whether the facts and circumstances set forth
    in the affidavit establish probable cause. The Fourth Amendment to the United
    States Constitution provides:
    The right of the people to be secure in their
    persons, houses, papers, and effects, against unreasonable
    searches and seizures, shall not be violated; and no
    Warrants shall issue, but upon probable cause, supported
    by Oath or affirmation, and particularly describing the
    place to be searched, and the persons or things to be
    seized.
    U.S. Const. amend. IV.       The “common-sense, practical question” of whether
    probable cause exists must be determined by applying a “totality of the
    circumstances” test. Illinois v. Gates, 
    462 U.S. 213
    , 230, 
    103 S. Ct. 2317
    , 2328, 76 L.
    Ed. 2d 527, 543 (1983); State v. Arrington, 
    311 N.C. 633
    , 637, 641, 
    319 S.E.2d 254
    ,
    257 (1984). Thus,
    “[t]he task of the issuing magistrate is simply to make a
    practical, common-sense decision whether, given all the
    circumstances set forth in the affidavit before him,
    including the ‘veracity’ and ‘basis of knowledge’ of persons
    supplying hearsay information, there is a fair probability
    that contraband or evidence of a crime will be found in a
    -6-

    Opinion of the Court
    particular place. And the duty of a reviewing court is
    simply to ensure that the magistrate had a ‘substantial
    basis for . . . conclud[ing]’ that probable cause existed.

    ,

    2332, 76 L. Ed. 2d at 548
    (third and fourth alterations in original)).
    “ ‘[P]robable cause requires only a probability or substantial chance of criminal
    activity, not an actual showing of such activity.’ ” State v. Riggs, 
    328 N.C. 213
    , 219,

    , 433 (1991) (emphasis omitted) (quoting

    n.13,
    103 S. Ct. at 2335 
    n.13, 76 L. Ed. 2d at 552 
    n.13). This commonsense, practical
    inquiry is to be based upon “ ‘the factual and practical considerations of everyday
    life on which reasonable and prudent men, not legal technicians, act.’ ” 
    Id. (quoting Gates,
    462 U.S. at 
    231, 103 S. Ct. at 2328
    , 76 L. Ed. 2d at 544).
    Further, “a magistrate is entitled to draw reasonable inferences from the
    material supplied to him by an applicant for a warrant.” State v. Sinapi, 
    359 N.C. 394
    , 399, 
    610 S.E.2d 362
    , 365 (2005) (citing 
    Riggs, 328 N.C. at 221
    , 400 S.E.2d at
    434). And we acknowledge that “ ‘great deference should be paid a magistrate’s
    determination of probable cause and that after-the-fact scrutiny should not take the
    form of a de novo review.’ ” 
    Id. at 398,

    Arrington, 311 N.C. at 638
    , 319 S.E.2d at 258). This deference, however, is not without limitation.
    A reviewing court has the duty to ensure that a magistrate does not abdicate his or
    her duty by “mere[ly] ratif[ying] . . . the bare conclusions of [affiants].”

    STATE V. BENTERS
    Opinion of the Court
    125, 130-31, 
    191 S.E.2d 752
    , 756 (1972) (“Probable cause cannot be shown by
    affidavits which are purely conclusory . . . .” (citation and internal quotation marks
    omitted)); see also United States v. Leon, 
    468 U.S. 897

    , 3416,
    
    82 L. Ed. 2d 677
    , 693 (1984) (“[C]ourts must . . . insist that the magistrate purport
    to perform his neutral and detached function and not serve merely as a rubber
    stamp for the police.”) (citations and internal quotation marks omitted), superseded
    in part by Fed. R. Crim. P. 41(e).
    Because the affidavit is based in part upon information received by Detective
    Hastings from a source unknown to Lieutenant Ferguson, we must determine the
    reliability of the information by assessing whether the information came from an
    informant who was merely anonymous or one who could be classified as confidential
    and reliable. State v. Hughes, 
    353 N.C. 200
    , 203, 
    539 S.E.2d 625
    , 628 (2000). This
    Court has explained that statements against an informant’s penal interests and
    statements given by an informant with a history of providing reliable information to
    law enforcement carry greater weight for purposes of establishing reliability. 
    Id. at 204,
    539 S.E.2d at 628-29; 
    Riggs, 328 N.C. at 219
    , 400 S.E.2d at 433 (discussing
    informant reliability based on an informant’s “track record”); State v. Beam, 
    325 N.C. 217
    , 221, 
    381 S.E.2d 327
    , 330 (1989) (acknowledging the credibility of
    statements against penal interest (citation omitted)); 
    Arrington, 311 N.C. at 641
    ,
    319 S.E.2d at 259 (discussing the credibility of statements against penal interest);
    see 
    Hughes, 353 N.C. at 204
    , 539 S.E.2d at 628 (suggesting that “other indication[s]
    -8-
    STATE V. BENTERS
    Opinion of the Court
    of reliability” may suffice even in the absence of statements against penal interest
    or an informant’s history of giving reliable information).
    When sufficient indicia of reliability are wanting, however, we evaluate the
    information based on the anonymous tip standard. 
    Hughes, 353 N.C. at 205
    , 539
    S.E.2d at 629. An anonymous tip, standing alone, is rarely sufficient, but “the tip
    combined with corroboration by the police could show indicia of reliability that
    would be sufficient to [pass constitutional muster].” 
    Id. (citing Alabama
    v. White,
    
    496 U.S. 325
    , 329, 
    110 S. Ct. 2412
    , 2416, 
    110 L. Ed. 2d 301
    , 308 (1990)). Thus, “a
    tip that is somewhat lacking in reliability may still provide a basis for [probable
    cause] if it is buttressed by sufficient police 
    corroboration.” 353 N.C. at 207
    , 539
    S.E.2d at 630 (citation omitted). Under this flexible inquiry, when a tip is less
    reliable, law enforcement officers carry a greater burden to corroborate the
    information. Id. at 
    205, 539 S.E.2d at 629
    . As compared with the less demanding
    reasonable suspicion standard, probable cause requires both a greater quantity and
    higher quality of information. 
    White, 496 U.S. at 329-30
    , 110 S. Ct. at 2416, 110 L.
    Ed. 2d at 308-09.
    As a preliminary matter, the State argues that it did not concede the
    illegality of the law enforcement officers’ entry onto defendant’s property to conduct
    a “knock and talk interview” at the back door of defendant’s residence or at an
    outbuilding from which officers heard music playing. See Benters, ___ N.C. App. at
    ___, 750 S.E.2d at 588 (majority) (“The State concedes that the ‘knock and talk’
    -9-
    STATE V. BENTERS
    Opinion of the Court
    entry onto defendant’s property was an illegal search . . . .”); see also id. at ___, 750
    S.E.2d at 590 (“As previously acknowledged by the State, this entry was illegal and
    thus the marijuana smell and plastic coverings could not be properly considered in
    seeking a search warrant.”).      Having reviewed the opinion below and record on
    appeal, including the State’s briefs to the Court of Appeals, we observe that the
    State did not expressly concede the point, but rather “[a]ssum[ed], without deciding,
    that the trial court correctly determined that the officers’ entry onto defendant’s
    property to conduct a ‘knock and talk’ – and further entry onto the property to
    locate or engage any person near the building from which the music was emanating
    – was illegal, and omitting this information from the warrant, the warrant was
    nevertheless valid.” Nonetheless, by failing to preserve the issue for appeal or to
    present any argument whatever, the State limits its arguments and our scope of
    review to the first three paragraphs of the affidavit. N.C. Rs. App. P. 10(b), 16(b),
    28(b)(6).
    In its principal argument on appeal, the State argues that the majority of the
    panel of the Court of Appeals erred by concluding that the first three paragraphs of
    the affidavit failed to establish probable cause upon which a search warrant could
    issue.    In support of this argument, the State contends that the tip given to
    Detective Hastings and relayed to Lieutenant Ferguson had sufficient indicia of
    reliability to provide probable cause.         Even if the tip is considered wholly
    anonymous, the State suggests that law enforcement officers independently
    -10-
    STATE V. BENTERS
    Opinion of the Court
    corroborated the tip through Lieutenant Ferguson’s prior personal knowledge of
    defendant and the property, the subpoenaed Progress Energy utility reports, and
    the officers’ personal observations of defendant’s gardening supplies.      The State
    further argues that the officers’ reliance upon the tip and their interpretation of the
    investigation must “be viewed through the eyes of a narcotics officer with the
    appropriate training and experience that both Lieutenant Ferguson and Detective
    Hastings appeared to have.”
    With respect to whether the source of the information at issue should be
    treated as a reliable, confidential informant or an anonymous informant, the
    affidavit states the following relevant information: (1) the affiant’s name; (2) the
    name of the detective from whom the affiant received the tip; (3) that the detective
    “met with a confidential and reliable source”; and (4) that the source informed the
    detective about an indoor marijuana growing operation at a house and other
    buildings on property owned by defendant.
    It is clear from the affidavit that the information provided does not contain a
    statement against the source’s penal interest. Nor does the affidavit indicate that
    the source previously provided reliable information so as to have an established
    “track record.” Thus, the source cannot be treated as a confidential and reliable
    informant on these two bases. 
    Hughes, 353 N.C. at 204
    , 539 S.E.2d at 628; 
    Riggs, 328 N.C. at 219

    Beam, 325 N.C. at 221

    Arrington, 311 N.C. at 641
    -42, 319 S.E.2d at 259-60. Nonetheless, the State argues
    -11-
    STATE V. BENTERS
    Opinion of the Court
    that because Detective Hastings met “face-to-face” with the source, the source
    should be considered more reliable, and we acknowledge that Lieutenant Ferguson
    is entitled to rely upon information reported to him by Detective Hastings.         See
    State v. Vestal, 
    278 N.C. 561
    , 576, 
    180 S.E.2d 755
    , 765 (1971) (citation omitted),

    , 
    94 S. Ct. 157
    , 
    38 L. Ed. 2d 114
    (1973).
    We already have addressed this issue on similar facts presented in Hughes.
    There we explained that the law enforcement officer who filed the affidavit “had
    never spoken with the informant and knew nothing about the informant other than
    [his captain’s] claim that he was a confidential and reliable informant.” 
    Hughes, 353 N.C. at 204
    , 539 S.E.2d at 628. Although the captain in Hughes received the tip
    from a phone call rather than a face-to-face meeting, the captain told the affiant
    that the confidential source was reliable.         
    Id. at 201,
    539 S.E.2d at 627.   We
    concluded that the source must be analyzed under the anonymous tip standard
    because the affiant had nothing more than the captain’s “conclusory statement that
    the informant was confidential and reliable,” 
    id. at 204,
    539 S.E.2d at 629. We see
    no reason to reach a different result here. The affidavit does not suggest Lieutenant
    Ferguson was acquainted with or knew anything about Detective Hastings’s source
    or could rely on anything other than Detective Hastings’s statement that the source
    was confidential and reliable.

    informant] would be held accountable if her tip proved to be false” (citation
    omitted)).
    In contrast, the affidavit here fails to establish the basis for Detective
    Hastings’s appraisal of his source’s reliability, including the source’s demeanor or
    degree of potential accountability. The affidavit does not disclose whether Detective
    Hastings met his source privately, or publicly and in uniform such that the source
    could risk reprisal. Moreover, nothing in the affidavit suggests the basis of the
    source’s knowledge. We previously have explained that
    [i]n the absence of a statement detailing the manner in
    -13-
    STATE V. BENTERS
    Opinion of the Court
    which the information was gathered, it is especially
    important that the tip describe the accused’s criminal
    activity in sufficient detail that the magistrate may know
    that he is relying on something more substantial than a
    casual rumor circulating in the underworld or an
    accusation based merely on an individual’s general
    reputation.
    State v. Edwards, 
    286 N.C. 162
    , 168, 
    209 S.E.2d 758
    , 762 (1974) (citation and
    quotation marks omitted).
    Accordingly, we hold that Detective Hastings’s source of information is an
    anonymous informant.        The tip, as averred, amounts to little more than a
    conclusory rumor, and the State is not entitled to any great reliance on it.
    Therefore, the officers’ corroborative investigation must carry more of the State’s
    burden to demonstrate probable cause. See 
    White, 496 U.S. at 330
    , 110 S. Ct. at
    
    2416, 110 L. Ed. 2d at 309
    (“[I]f a tip has a relatively low degree of reliability, more
    information will be required to establish the requisite quantum of suspicion than
    would be required if the tip were more reliable.”); 
    Hughes, 353 N.C. at 205
    , 539
    S.E.2d at 629.
    The State directs our attention to several factors which it believes sufficiently
    corroborate the anonymous tip. These factors include: (1) Lieutenant Ferguson’s
    knowledge of defendant and his property resulting “from a criminal case involving a
    stolen flatbed trailer”; (2) utility records for the preceding twenty-four months
    subpoenaed by Detective Hastings that “indicated that Glenn Benters is the current
    subscriber and the kilowatt usage hours are indicative of a marijuana grow
    -14-
    STATE V. BENTERS
    Opinion of the Court
    operation based on the extreme high and low kilowatt usage”; and (3) the law
    enforcement officers’ observations of “multiple items in plain view that were
    indicative of an indoor marijuana growing operation,” including “potting soil,
    starting fertilizer, seed starting trays, plastic cups, metal storage racks, and
    portable pump type sprayers,” in the absence of “any gardens or potted plants
    located around the residence.”    The State argues that all of these corroborative
    factors must be “viewed through the eyes of” the officers in light of their training
    and experience.
    The State suggests that law enforcement officers’ “corroboration of mundane
    matters” conveyed by the informant, such as defendant’s name and address,
    increases the reliability of the tip. We agree, but the State’s proposition has limited
    effect. On the fluid balance prescribed by the Supreme Court, a less specific or less
    reliable tip requires greater corroboration to establish probable cause. 
    White, 496 U.S. at 329-30
    , 110 S. Ct. at 
    2416, 110 L. Ed. 2d at 308-09
    (citations omitted). Thus,
    some measure of reliability flows from law enforcement officers’ corroboration of
    mundane matters, but such corroboration supports a finding of probable cause only
    to a coterminous extent.    Here, the officers corroborated defendant’s name and
    address through subpoenaed Progress Energy records showing defendant as the
    current subscriber and through Lieutenant Ferguson’s knowledge of defendant and
    his address from a prior, unrelated criminal charge. The officers’ corroboration
    tends to show they know defendant’s identity and address, although it is not clear
    -15-
    STATE V. BENTERS
    Opinion of the Court
    that defendant ever resides at this address. Thus, the officers’ corroboration adds a
    small measure of reliability to the anonymous tip, but does little toward
    establishing probable cause.
    With respect to the subpoenaed Progress Energy utility records, we note that
    this Court has not yet addressed law enforcement officers’ use of electricity usage
    records in an affidavit for a search warrant related to an alleged indoor marijuana
    growing operation. We are cognizant that we must view the records as part of the
    totality of the circumstances. As we consider this novel issue before our Court,
    however, we momentarily consider in isolation the rules regarding this source of
    information. Having reviewed numerous state and federal authorities that have
    assessed an affiant’s use of utility records, we acknowledge that these records can
    provide powerful support for probable cause in applications for search warrants,
    and we adopt the following principles.
    In a totality of the circumstances inquiry, the value to be accorded to energy
    records is, of course, flexible. The weight given to power records increases when
    meaningful comparisons are made between a suspect’s current electricity
    consumption and prior consumption, or between a suspect’s consumption and that
    of nearby, similar properties. See, e.g., United States v. Kattaria, 
    553 F.3d 1171
    ,
    1174 (8th Cir.) (en banc) (per curiam) (Probable cause existed when the affidavit
    showed, inter alia, that “between November 2003 and April 2004, the [defendant’s]
    residence . . . consumed between 1890 and 2213 kilowatt hours of electricity per

    , at *1-2 (M.D.N.C. Sept. 14, 2012) (probable cause found when the affidavit

    higher than nine similarly sized houses on his street); State v. Hook,

    839 P.2d 1274
    , 1276 (1992) (finding probable cause when the affidavit, inter alia,
    “recited in detail the power usage, the times of residence by the defendant, previous
    usage by former occupants, normal residential usage, and comparisons as to these
    facts”); State v. Lemonds, 
    160 N.C. App. 172
    , 179, 
    584 S.E.2d 841

    (probable cause found when, inter alia, electric bills for the defendant’s first home
    “revealed a dramatic increase in electricity usage during the period of [the]

    which he moved during the course of the investigation, revealed a dramatic increase
    after his occupancy “when compared with the previous occupant’s bills for the same
    time of year”).
    By contrast, little to no value should be accorded to wholly conclusory, non-
    comparative allegations regarding energy usage records. See, e.g., State v. Kaluza,
    
    272 Mont. 404
    , 409, 
    901 P.2d 107
    , 110 (1995) (concluding probable cause was not

    Here Lieutenant Ferguson averred that “Detective Hastings has extensive
    training and experience with indoor marijuana growing investigations on the state
    and federal level,” and that Detective Hastings had subpoenaed defendant’s
    Progress Energy power records. Lieutenant Ferguson then summarily concluded
    that “the kilowatt usage hours are indicative of a marijuana grow operation based
    on the extreme high and low kilowatt usage.” As explained above, the absence of
    any comparative analysis severely limits the potentially significant value of
    defendant’s utility records.

    unsupported allegations do little to establish probable cause independently or by
    corroborating the anonymous tip. 
    Campbell, 282 N.C. at 130-31
    , 191 S.E.2d at 756.
    We acknowledge that investigating officers or a reviewing magistrate may
    have some degree of suspicion regarding defendant’s “extreme high and low
    -18-
    STATE V. BENTERS
    Opinion of the Court
    kilowatt usage” given that defendant “is not currently living at the residence.”
    These unspecified extremes also may be explained, however, by wholly innocent
    behavior such as defendant’s intermittently visiting his property.              Thus, these
    circumstances may justify additional investigation, but they do not establish
    probable cause.
    We turn next to the officers’ observations of multiple gardening items on
    defendant’s property in the absence of exterior gardens or potted plants.                In
    relevant part, the affidavit provides that law enforcement officers
    observed from outside of the curtilage multiple items in
    plain view that were indicative of an indoor marijuana
    growing operation. The items mentioned above are as
    followed [sic]; potting soil, starting fertilizer, seed starting
    trays, plastic cups, metal storage racks, and portable
    pump type sprayers. Detectives did not observe any
    gardens or potted plants located around the residence.
    Nothing here indicates “a ‘fair probability that contraband or evidence of a
    crime will be found in a particular place’ ” beyond Lieutenant Ferguson’s wholly
    conclusory allegations.

    gardening supplies were, or appeared to have been, used, or whether the supplies
    appeared to be new, or old and in disrepair.         Thus, amid a field of speculative
    possibilities, the affidavit impermissibly requires the magistrate to make what
    otherwise might be reasonable inferences based on conclusory allegations rather

    134 L. Ed. 2d 911
    , 920-21 (1996) (observing that “a police officer views the facts through the lens
    of his police experience and expertise”). The affidavit here sets forth Lieutenant
    Ferguson’s training and experience, including his having been a sworn law
    enforcement officer since 1998, his employment with the Vance County Sheriff’s
    Office, his current employment as a Detective Lieutenant in the Criminal
    Investigations and Narcotics Division, his training in “Search[ ] and Seizure, Search
    and Seizure in North Carolina, Criminal Investigations, [and] Search Warrant
    Preparation,” and his completion of the “Drug Law Enforcement Training Program
    through the Federal Law Enforcement Training Center.” The affidavit also states
    that “Detective Hastings has extensive training and experience with indoor
    marijuana growing investigations on the state and federal level.”       We are not
    convinced that these officers’ training and experience are sufficient to balance the
    quantitative and qualitative deficit left by an anonymous tip amounting to little
    more than a rumor, limited corroboration of facts, non-comparative utility records,
    observations of innocuous gardening supplies, and a compilation of conclusory
    allegations. See 
    White, 496 U.S. at 329-30

    Opinion of the Court
    09. Furthermore, we are unaware of any precedent that would permit, much less
    require, such a heavy reliance upon officers’ training and experience as the State
    calls for here.
    Taking the relevant factors together in view of the totality of the
    circumstances, we conclude that the officers’ verification of mundane information,
    Detective Hastings’s statements regarding defendant’s utility records, and the
    officers’ observations of defendant’s gardening supplies are not sufficiently
    corroborative of the anonymous tip or otherwise sufficient to establish probable
    cause,    notwithstanding   the   officers’     professional   training   and   experience.
    Furthermore, the material allegations set forth in the affidavit are uniformly
    conclusory and fail to provide a substantial basis from which the magistrate could
    determine that probable cause existed.

    deference should be paid a magistrate’s determination of probable cause,” 
    Sinapi, 359 N.C. at 399
    , 610 S.E.2d at 365 (citation and quotation marks omitted), we hold
    the affidavit at issue is insufficient to establish probable cause.
    In its remaining arguments on appeal, the State notes that the trial court
    took additional evidence once defendant challenged the search. The State contends
    that the Court of Appeals erred by relying upon facts elicited at the hearing that
    -21-
    STATE V. BENTERS
    Opinion of the Court
    went beyond “the four corners of [the] warrant.” The State argues that if additional
    evidence is considered, the record demonstrates that the officers had probable cause
    to support a search warrant independent of any information gathered during the
    allegedly illegal entry onto defendant’s property. The State argues, moreover, that
    had the entry not occurred, “the police unquestionably would have pursued the
    investigation until it reached a successful conclusion,” making it “inevitable” that
    the marijuana and other items would have been discovered pursuant to a search
    warrant supported by probable cause.
    We acknowledge that the Court of Appeals majority and dissenting opinions
    made glancing references to additional evidence found during defendant’s
    suppression hearing and it was error to consider this evidence, but in light of our
    holding and analysis based solely upon the affidavit, we do not believe these errors
    warrant reversal. Therefore, we need not consider the State’s conditional argument
    regarding inevitable discovery. See, e.g., Poore v. Poore, 
    201 N.C. 791
    , 792 
    161 S.E. 532
    , 533 (1931) (“It is no part of the function of the courts . . . to give advisory
    opinions . . . .”).
    For the reasons set forth above, we affirm the opinion of the Court of Appeals.
    AFFIRMED.

    No. 5A14 – State v. Benters
    Justice NEWBY dissenting.
    In this case we address the level of corroboration required to substantiate an
    informant’s tip such that probable cause exists to obtain a search warrant for a
    defendant’s property.   The majority concludes that, under the anonymous tip
    standard, “the State is not entitled to any great reliance” on a tip from a known
    informant. In doing so, the majority ignores the fact that the informant clearly was
    not anonymous and incorrectly affords his tip the same weight as if he were
    completely unknown to police. Because a tip provided to police by an identified
    informant is inherently more reliable than a completely anonymous tip, it should
    require less independent corroboration. Although purportedly applying a “common
    sense” approach, the majority’s rigid, formalistic dissection of the evidence
    corroborating the tip undermines the purpose of the required totality of the
    circumstances test. Here, the information provided in the tip, most of which was
    corroborated by other evidence, under a common sense application of the totality of
    the circumstances, establishes probable cause to believe that defendant was
    growing marijuana on his property.     Therefore, the warrant was valid, and the
    search did not violate the Fourth Amendment. Accordingly, I respectfully dissent.
    The Fourth Amendment to the Constitution of the United States contains a
    guarantee against unreasonable searches and seizures and provides that “no
    Warrants shall issue, but upon probable cause.” In State v. Arrington our Court
    adopted the Supreme Court of the United States’ “totality of the circumstances” test
    STATE V. BENTERS
    NEWBY, J., dissenting
    for determining when probable cause exists:
    “The task of the issuing magistrate is simply to make a
    practical, common-sense decision whether, given all the
    circumstances set forth in the affidavit before him,
    including the ‘veracity’ and ‘basis of knowledge’ of persons
    supplying hearsay information, there is a fair probability
    that contraband or evidence of a crime will be found in a
    particular place.”

    Tips from informants can establish probable cause if they are reliable. See

    Tips from informants with a proven track record with police are considered
    trustworthy and can establish probable cause standing alone when the affidavit
    states that the informant is reliable and provides factual grounds to support that
    belief. See State v. Isleib, 
    319 N.C. 634
    , 635, 639, 
    356 S.E.2d 573
    , 574-75, 577 (1987)

    informant had provided information to police on three prior occasions that had led
    -2-
    STATE V. BENTERS

    to arrests and convictions).    On the other hand, anonymous tips are generally
    insufficient standing alone to establish probable cause. Alabama v. White,

    110 S. Ct. 2412
    , 2415-16, 
    110 L. Ed. 2d 301
    , 308 (1990).
    Not all anonymous tips, however, are created equal. Some bear more indicia
    of reliability than others, and in evaluating the totality of the circumstances, “the
    indicia of the tip’s reliability are certainly among the circumstances that must be
    considered.” State v. Maready,

    32 L. Ed. 2d 612
    , 617 (1972))).      In a recent decision, the United States
    Supreme Court observed that even a wholly anonymous tip, without more, “can
    demonstrate sufficient indicia of reliability to provide reasonable suspicion to make
    [an] investigatory stop.” Navarette v. California, ___ U.S. ___, ___,

    standard, there is a sliding scale, and the extent of independent corroboration
    required to render a tip reliable becomes a factual determination, “tak[ing] into
    account all the facts surrounding [the] tip.”

    As illustrated by Navarette, a tipster is not treated as wholly unreliable
    simply because the affidavit does not disclose the tipster’s prior experience with law
    enforcement. It follows that less independent verification is needed to substantiate
    a tip from an informant who is readily identifiable by police than one who is
    completely anonymous. See

    a face-to-face encounter and was, therefore, not completely anonymous); see also

    (“Where the informant is known . . . , an officer can judge
    the credibility of the tipster firsthand and thus confirm whether the tip is
    sufficiently reliable . . . .”). Moreover, because affidavits are practical documents
    and the existence of probable cause is a commonsense determination, the summary
    nature of the affidavit becomes less important when a tip shows some indicia of
    reliability and is corroborated by independent investigation.
    Here the majority’s analysis recognizes that the informant was known and
    identified to police, yet it ignores that crucial fact to conclude instead that he “is an
    anonymous informant” whose tip “amounts to little more than a conclusory rumor.”
    However, the affidavit states that “within the past week [an officer] met with a
    confidential and reliable source of information that told him an indoor marijuana
    growing operation was located at [defendant’s property].”           (Emphasis added.)
    Because the police knew the informant’s identity, the informant’s tip had some
    degree of reliability at the outset. Though the tip, at face value, may not be enough
    on its own to establish probable cause, the tip is more reliable than if the informant
    were completely anonymous. See 
    Maready, 362 N.C. at 619-20
    , 669 S.E.2d at 567-
    68. Therefore, even without specific details on why the informant was a reliable
    source of information, the tipster should be afforded greater weight in the totality of
    the circumstances than if he were unknown and unidentified. See

    officers from personal observation’ including those that do not necessarily
    corroborate or refute the informant’s statements.” (internal citation omitted)).
    The detectives’ subsequent investigation into the informant’s allegations
    sufficiently corroborated the tip that defendant was conducting a marijuana
    growing operation, and when taken together and viewed through the lens of
    common sense, the tip and corroborating evidence detailed in the first three
    paragraphs of the affidavit established “ ‘a fair probability that contraband or
    evidence of a crime [would] be found’ ” on defendant’s property.

    , 319 S.E.2d at 258 (quoting 
    Gates, 462 U.S. at 238
    , 103 S. Ct. at 2332, 76 L.
    Ed. 2d at 548).    In the tip, the informant did not simply say that there was a
    marijuana growing operation. He identified defendant by name and appearance,
    provided defendant’s address, specified that defendant was not currently living at
    the residence, and described the buildings that defendant was using to house the
    marijuana growing operation. The affiant was also familiar with defendant and his
    property from a prior, unrelated criminal case. Based on the tip, which already bore
    some indicia of reliability, detectives obtained utility records for the address and
    learned that defendant was the current subscriber, confirming a detail provided by
    the informant. Furthermore, according to a law enforcement officer with “extensive
    training and experience with indoor marijuana growing investigations on the state
    and federal level,” the two year history of “extreme high and low kilowatt usage”
    -6-
    STATE V. BENTERS
    NEWBY, J., dissenting
    was “indicative of a marijuana grow operation,” just as the informant said.
    The majority concludes for the first time that the opinion of a trained and
    experienced detective who analyzed the power usage is not sufficient, absent a
    comparative analysis, despite the fact that the detective reviewed power records for
    the preceding two years. In doing so, the majority ignores the expertise of trained
    and experienced law enforcement officers.          Under the majority’s reasoning,
    detectives should have invaded the privacy of innocent, neighboring landowners by
    obtaining their power records in order to conduct a comparative analysis. Even so,
    detectives here did not rely solely on the utility bills to establish probable cause;
    rather, the unusual power usage was just another piece of evidence that helped
    bolster the informant’s reliability and corroborate his tip that defendant was
    housing an indoor marijuana growing operation.
    Detectives further confirmed the information in the tip by conducting
    surveillance of defendant’s property. Despite the noticeable absence of gardens or
    potted plants around the property, officers observed multiple horticultural items in
    plain view, including “potting soil, starting fertilizer, seed starting trays, plastic
    cups, metal storage racks, and portable pump type sprayers.”         Based on their
    training and experience, detectives determined that these objects were consistent
    with a marijuana growing operation. This observation is yet another circumstance
    establishing the informant’s reliability and lending support to the tip that
    defendant was operating an indoor marijuana growing operation.

    Moreover, the fact that any of the corroborating evidence can be explained by
    innocent behavior does not mean it cannot also be used to establish probable cause,
    as the majority suggests. The possibility of innocent behavior does not rule out
    probable cause.

    n.13 (“[I]nnocent behavior frequently will provide the basis for a showing of
    probable cause; to require otherwise would be to sub silentio impose a drastically
    more rigorous definition of probable cause than the security of our citizens’
    demands. . . . In making a determination of probable cause the relevant inquiry is
    not whether particular conduct is ‘innocent’ or ‘guilty,’ but the degree of suspicion
    that attaches to particular types of noncriminal acts.” (internal citation omitted)).
    Applying the required commonsense approach to the totality of the
    circumstances, the information contained in the affidavit established a “fair
    probability” that defendant was conducting an indoor marijuana growing operation.
    Detectives received a tip from an identified informant who provided details about
    defendant, his property, and his indoor marijuana growing operation.              In a
    subsequent investigation, a trained and experienced detective concluded that
    defendant’s power usage was indicative of a marijuana growing operation.
    Furthermore, surveillance of defendant’s property produced evidence consistent
    with a marijuana growing operation. This circumstantial evidence unequivocally
    supported the initial, detailed tip.    Even under an anonymous tip standard, a
    known informant’s tip must be afforded more weight than if he were wholly
    -8-

    NEWBY, J., dissenting
    anonymous.      Each piece of independent, corroborating evidence thereafter
    substantiated the informant’s reliability, and the tip, combined with the
    corroborating evidence, provided a sufficient basis for the warrant. Therefore, the
    search was lawful. Accordingly, I respectfully dissent.
