    Indictments found and returned in the Superior Court
    Department on October 31, 2013.
    A pretrial motion to suppress evidence was heard by Thomas
    P. Billings, J., and the cases were tried before him.
    Steven J. Rappaport for the defendant.
    Clarence H. Brown, Assistant District Attorney, for the
    Commonwealth.
    HENRY, J.   After a jury trial in Superior Court, the
    defendant, Radhames Gonzalez, was convicted of possession of
    cocaine with intent to distribute, carrying a firearm without a
    2
    license, possession of ammunition without a firearm
    identification card, possession of a large capacity feeding
    device, and possession of a large capacity weapon during the
    commission of a felony.1    The defendant argues that (1) his
    motion to suppress should have been allowed because the
    information supplied by a confidential informant (CI) did not
    justify the investigatory stop of his motor vehicle; and (2) the
    admission in evidence of a substitute chemist's testimony
    deprived the defendant of his right to "confront" the witness.
    We affirm.
    Background.     We set forth the facts as found by the motion
    judge, supplemented where necessary with uncontroverted evidence
    drawn from the record of the suppression hearing.     See
    Commonwealth v. Watson, 
    430 Mass. 725
    , 726 n.5 (2000).
    Sergeant William West of the Billerica police department
    testified that he had been a patrol sergeant for two years, and
    that he had formerly been a detective in the criminal bureau for
    sixteen years.     As a detective, he had investigated all types of
    crimes including narcotics offenses and had worked with
    informants "no less than a hundred times."    In June, 2013, about
    one year after he had become a sergeant, West was contacted by a
    1 The defendant then waived his right to a jury and was
    tried before the judge on sentence enhancements connected with
    two of the firearms charges. A motion for a required finding of
    not guilty was allowed as to both enhancements.
    3
    CI with whom West had worked on more than one occasion when he
    was a detective.
    On this occasion, the CI provided a description of a man
    who went by the name of "Eddie," later identified as the
    defendant, who was dealing heroin and cocaine in and around the
    Gaelic Club (club) in Lowell.   The CI described the defendant as
    a Dominican male who drove a white Buick Rendezvous CXL sport
    utility vehicle bearing license plate 676 NB4.   The CI indicated
    that on Friday nights the defendant used the club as a base of
    operation and that the CI personally observed the defendant make
    cocaine sales in the club's bathroom.    The CI also indicated
    that the defendant would receive telephone calls and travel to
    individuals' homes to sell drugs.   The CI also told West that
    the defendant usually carried a firearm and the CI believed the
    defendant did not have a valid driver's license.
    Because West was no longer involved in narcotics
    investigations and because the club was in Lowell, not
    Billerica, he passed the CI's tip and contact number to Sergeant
    Noone of the Lowell police department.    West explained to Noone
    that the CI was an informant who had been "signed up by
    Billerica" and had been reliable in the past, including having
    given information that led to arrests and seizures.    Noone
    assigned the matter to Lowell police Detective Rafael Rivera.
    When Rivera spoke by phone with the CI, the CI repeated what he
    4
    had disclosed to West and that he had seen the defendant in the
    club only a "couple of days before," in possession of drugs and
    his gun.   Rivera ran the license plate number the CI had given
    him and the records showed that the vehicle was registered to
    Kennedy Ruiz-Mejia.2
    On Friday, June 28, 2013, at about 7:25 P.M., Rivera and
    three other undercover officers, in four separate vehicles, set
    up surveillance around the club.     Rivera saw a vehicle matching
    the make, model, license plate, and color supplied by the CI.
    After a few minutes, a man matching the description of "Eddie"
    exited the club, got into the vehicle, and drove away.     When the
    vehicle turned into a gasoline station, Lowell police Detective
    Michael Kandrotas pulled in behind it, activating the concealed
    lights and siren on his unmarked cruiser.
    Kandrotas exited his vehicle and, as he approached,
    observed the driver make a quick movement to his right, as if to
    toss something into the back seat.    Because the defendant had
    been reported to carry a firearm, Kandrotas had the defendant
    exit the vehicle.   Rivera joined Kandrotas and recognized the
    defendant as someone he knew from prior narcotics
    investigations.
    2 After the defendant was arrested, Rivera learned that
    Ruiz-Mejia had passed away in 2011.
    5
    Rivera confirmed through dispatch that the defendant did
    not have a current driver's license.   The defendant was placed
    under arrest for operating a vehicle without a license.     Rivera
    searched the defendant and found $5,100 on his person.    The
    defendant was transported to the police station.   During
    booking, it was determined that the defendant had an alias of
    Eddie Mambru.
    Because the defendant's vehicle was blocking a gasoline
    pump, and the police were going to search it, the police moved
    it across the street to a school parking lot after the defendant
    was arrested.   The Lowell inventory policy, which was introduced
    at the motion hearing, provides for the inventory and towing of
    a vehicle that was, or is, being used in the commission of a
    crime.   When police opened the rear door, they observed a loaded
    .40 caliber semiautomatic handgun poorly concealed in a sock on
    the floor.   In a second sock, police recovered twenty-seven
    bags, each containing a powder later confirmed to be cocaine.
    The motion judge found that the police had conducted an
    investigatory stop based on information supplied by the CI.     The
    judge recognized that in such circumstances, the CI's
    information must establish both the reliability and basis of
    knowledge prongs set forth under the Aguilar-Spinelli test.3    The
    3 Under the Aguilar-Spinelli test, "[t]o establish the
    reliability of the information under art. 14 [of the
    6
    judge reasoned that "'[b]ecause the standard is reasonable
    suspicion rather than probable cause, a less rigorous showing in
    each of these areas is permissible' . . . [and] independent
    police corroboration may 'make up for deficiencies in one or
    both of these factors.'"   Commonwealth v. Pinto, 
    476 Mass. 361
    ,
    364 (2017), quoting from Commonwealth v. Depina, 
    456 Mass. 238
    ,
    243 (2010).
    Applying this standard, the judge ruled that the CI's basis
    of knowledge was self-evident from the tip and founded on
    personal observation.   On the veracity prong, according to West,
    "The information [the CI] provided allowed [West] to seize
    various types of narcotics, make drug seizures and drug arrests,
    as well as seizing money, the proceeds of drug profits."
    Through cross-examination, defense counsel elicited that
    individuals who make controlled buys are considered to be
    "informant[s]"; that "if [a] person had, in fact, made a series
    of purchases on behalf of the Billerica [p]olice [d]epartment,
    [West] could honestly say that that individual had provided
    [West] with information that if it did lead to arrest, to arrest
    Massachusetts Declaration of Rights], 'the Commonwealth must
    show the basis of knowledge of the source of the information
    (the basis of knowledge test) and the underlying circumstances
    demonstrating that the source of the information was credible or
    the information reliable (veracity test).'" Commonwealth v.
    Anderson, 
    461 Mass. 616
    , 622, cert. denied, 
    568 U.S. 946
     (2012),
    quoting from Commonwealth v. Mubdi, 
    456 Mass. 385
    , 395-396
    (2010). See Aguilar v. Texas, 
    378 U.S. 108
     (1964); Spinelli v.
    United States, 
    393 U.S. 410
     (1969).
    7
    and seizure . . . "; and that, specifically, this CI had
    previously made controlled buys for the Billerica police
    department.   The Commonwealth did not ask West on redirect
    examination whether the CI previously had been a tipster and not
    merely a controlled buyer.    The judge specifically found:     "I
    understand [West's] testimony to mean that the CI supplied
    substantive information as well as helping with controlled
    buys."   The judge also found that knowledge of the CI's past
    track record of reliability with Billerica, which was conveyed
    to Lowell, was sufficient to "satisf[y] the veracity test."
    Discussion.    1.   Motion to suppress.   a.   The stop.    "In
    reviewing a denial of a motion to suppress, we accept the
    judge's subsidiary findings of fact absent clear error, but
    conduct an independent review of the judge's ultimate findings
    and conclusions of law."     Commonwealth v. Washington, 
    449 Mass. 476
    , 480 (2007).
    Here, because there is no live dispute regarding the CI's
    basis of knowledge, given the CI's personal observations of the
    defendant in possession of drugs and a gun only days prior to
    the tip, we focus on the evidence of the CI's veracity.        The
    motion judge gave West's testimony regarding the CI's prior
    track record its plain and ordinary meaning, namely that on more
    than one previous occasion the CI had directly provided material
    information regarding violations of the law and, further, that
    8
    the CI provided "substantive information."   The judge's finding
    of fact comports with the language West used, the testimony that
    the informant had been reliable in the past, and the common
    situation presented in police work in which a CI provides
    material information regarding criminal violations and is then
    engaged to execute a controlled buy.4   See, e.g., Commonwealth v.
    Perez-Baez, 
    410 Mass. 43
    , 44-46 (1991) (recitation that
    informant had "provided information" previously that led to
    arrests and seizure of cocaine sufficiently established
    informant's veracity); Commonwealth v. Mendes, 
    463 Mass. 353
    ,
    365 (2012) (CI provided information and made controlled buy);
    Commonwealth v. Baldasaro, 
    62 Mass. App. Ct. 925
    , 926 (2004)
    (same); Commonwealth v. Velez, 
    77 Mass. App. Ct. 270
    , 273 (2010)
    (same); Commonwealth v. Lima, 
    80 Mass. App. Ct. 114
    , 119 n.5
    (2011) (same); Commonwealth v. Perez, 
    90 Mass. App. Ct. 548
    , 554
    (2016) (same).
    4 We also note that the CI knew specifically to telephone
    West to convey information regarding an individual's illegal
    drug sales in this case and that in anticipation of that
    conversation he had obviously noted the make, model,
    registration number, and color of that individual's vehicle,
    together with his method of operation, which suggests at least a
    likelihood that this was not his first tip. Additionally, we
    note that the detectives did corroborate several pieces of
    information from the CI before the stop, including the make,
    model, color, and license plate number of the vehicle that the
    defendant would be driving. However, corroboration of innocent
    details "only slightly" enhances the CI's reliability and is
    insufficient on its own to satisfy the veracity prong. See
    Commonwealth v. Lyons, 
    409 Mass. 16
    , 21 (1990).
    9
    The defendant contends that there was a possible
    alternative interpretation of West's testimony:     that in the
    past the CI could have been only a controlled buyer who had not
    provided information, which would be insufficient to establish
    the CI's veracity.    See Commonwealth v. Carrasquiello, 
    45 Mass. App. Ct. 772
    , 775-776 (1998) (differentiating between
    confidential informants as tipsters and controlled buyers for
    purposes of veracity).5    This argument is insufficient to show
    clear error in the motion judge's findings of fact.
    First, on a motion to suppress, "[q]uestions of credibility
    are the province of the motion judge who had the opportunity to
    observe the witnesses."    Commonwealth v. Tremblay, 
    460 Mass. 199
    , 205 (2011).     Second, and more importantly, that the
    Commonwealth or the motion judge might have asked what seems,
    possibly only in hindsight, an obvious follow-up question to
    confirm that the CI previously had been a tipster, rather than
    merely a controlled buyer, does not allow us to reverse.      Where
    the judge's finding "is plausible in light of the record viewed
    in its entirety, the [appellate court] may not reverse it even
    though convinced that had it been sitting as the [finder] of
    fact, it would have weighed the evidence differently.    Where
    5 Carrasquiello involved the question of probable cause for
    a search warrant for entry into a home, whereas this case
    involves the lesser standard of reasonable suspicion, and a
    Terry stop on the street. See Terry v. Ohio, 
    392 U.S. 1
     (1968).
    10
    there are two permissible views of the evidence, the
    factfinder's choice between them cannot be clearly erroneous."
    Edinburg v. Edinburg, 
    22 Mass. App. Ct. 199
    , 203 (1986), quoting
    from Anderson v. Bessemer City, 
    470 U.S. 564
    , 673-574 (1985).
    See Commonwealth v. Carr, 
    458 Mass. 295
    , 303 (2010);
    Commonwealth v. Gordon, 
    87 Mass. App. Ct. 322
    , 327 (2015).
    Moreover, that the defense interpretation of West's
    testimony may be possible does not make it probable or an
    inference the motion judge must draw.    A court considers the
    application for a search warrant, or here whether there was
    reasonable suspicion to conduct a stop, "in an ordinary,
    commonsense manner without hypertechnical analysis."    Perez-
    Baez, 
    410 Mass. at 46
    , quoting from Commonwealth v. Melendez,
    
    407 Mass. 53
    , 60 (1990) (Greaney, J., dissenting).     See
    Commonwealth v. Blake, 
    413 Mass. 823
    , 827 (1992) (search warrant
    affidavits should be "read as a whole, not parsed, severed, and
    subjected to hypercritical analysis").   "The standard of
    reasonable suspicion[, which is lower than the standard of
    probable cause,] does not require absolute certainty, but only
    'sufficient probability,' 'the sort of "common-sense
    conclusio[n] about human behavior" upon which "practical people"
    -- including government officials -- are entitled to rely.'"
    11
    Commonwealth v. Buccella, 
    434 Mass. 473
    , 486 (2001), quoting
    from New Jersey v. T.L.O., 
    469 U.S. 325
    , 346 (1985).6
    b.   The search of the vehicle.   Similarly unavailing is the
    defendant's claim that the search of the vehicle was
    unreasonable.   After the defendant was arrested, because his
    vehicle was blocking the pumps at a gasoline station that was
    open for business, the police moved the vehicle across the
    street.   Regardless of how the police described the ensuing
    search, the incriminating objects found during the search would
    have been discovered during the inevitable inventory search
    conducted before police had the vehicle towed.    See, e.g.,
    Commonwealth v. Miller, 
    366 Mass. 387
    , 389 (1974) (finding
    search constitutional even though "the officers did not
    completely and correctly articulate their grounds," where "from
    an objective standpoint probable cause existed"); Commonwealth
    6 At oral argument, the defendant added that the Lowell
    police could not rely on the track record of the CI established
    with the Billerica police department to establish the CI's
    reliability because they did not know the details of that track
    record and were not working collaboratively on the investigation
    with Billerica, citing Commonwealth v. Hawkins, 
    361 Mass. 384
    ,
    386-387 (1972) (collective knowledge doctrine did not apply
    because officers who seized bonds during search for drugs within
    the defendant's apartment were neither aware of theft of bonds
    nor working in concert with officers who had knowledge of the
    stolen bonds). Generally, we will not consider arguments not
    raised in a party's brief. Mass.R.A.P. 16(a)(4), as amended,
    
    367 Mass. 921
     (1975). In any event, the argument has no merit.
    Here, the Lowell police were informed that the CI was reliable
    by the Billerica police, and "[a] law enforcement officer who
    provides information is presumed credible." Commonwealth v.
    Watson, 
    36 Mass. App. Ct. 252
    , 253 n.1 (1994).
    12
    v. Somers, 
    44 Mass. App. Ct. 920
    , 922-923 (1998) (police
    discovery during automobile stop that defendant had no license
    warranted order that car be towed); Commonwealth v. Bienvenu, 
    63 Mass. App. Ct. 632
    , 634-635 (2005) (after police stopped car for
    safety infraction, subsequent tow and inventory search were
    proper because "neither defendant could lawfully drive the
    car").
    2.   Testimony of substitute chemist.   The defendant argues
    that testimony of a substitute chemist regarding the makeup of
    the substance seized from the defendant's vehicle violated his
    rights under the Sixth Amendment to the United States
    Constitution and art. 12 of the Massachusetts Declaration of
    Rights to confront and meet face to face the witnesses against
    him, and that the Commonwealth did not sufficiently prove the
    unavailability of the original chemist.7
    Testimony by an expert where he or she "draws upon testing
    conducted and results reached by other analysts[] who do not
    testify . . . is permissible provided that the testifying
    analyst 'reviewed the nontestifying analyst's work, . . .
    conducted an independent evaluation of the data,' and 'then
    expressed [his or] her own opinion, and did not merely act as a
    conduit for the opinions of others.'"   Commonwealth v. Jones,
    7 At trial, the prosecutor represented that the original
    chemist had left the laboratory and it was unknown whether she
    was still working as a chemist for the Commonwealth.
    13
    
    472 Mass. 707
    , 715 (2015), quoting from Commonwealth v.
    Greineder, 
    464 Mass. 580
    , 595 (2013).   See Greineder, supra at
    603 (no violation of Sixth Amendment or art. 12, even where
    testifying analyst based her opinion on test results of
    nontestifying analyst that were not admitted in evidence).
    Unavailability is not a prerequisite to calling a substitute
    chemist, provided the substitute chemist can be cross-examined
    on how he or she reached his or her opinion.   See id. at 594-
    599.
    The Commonwealth introduced the testimony of Paul Eyerly, a
    chemist with the State police drug unit in Sudbury, who
    testified as to his own independent opinion of the composition
    of the substances in question based on tests performed and
    results obtained by the original chemist.   The defendant cross-
    examined Eyerly regarding the basis on which he formed his
    opinion, the testing procedures used, and their susceptibility
    to human error.   We discern no error or any violation of the
    defendant's right to confront the witnesses against him under
    the United States Constitution or the Massachusetts Declaration
    of Rights.
    Judgments affirmed.
    RUBIN, J. (dissenting).     I dissent from the court's holding
    that the police had reasonable suspicion to stop the defendant.
    Since all evidence discovered was the fruit of an
    unconstitutional stop, the motion to suppress should have been
    allowed.
    In this case, a confidential informant described a
    Dominican male who drove a white Buick Rendezvous CXL sport
    utility vehicle of which the confidential informant recited the
    license plate number.     The confidential informant indicated that
    on Friday nights the man could be found at the Gaelic Club.        He
    said that the man used it as a base of operation, traveling to
    individuals' homes to sell drugs, and that he personally
    observed the man make cocaine sales in the club's bathroom.        The
    confidential informant also told the police that the man usually
    carried a firearm and that he believed the man did not have a
    valid driver's license.
    The police ran the license plate numbers and determined
    that the car was registered to a Kennedy Ruiz-Mejia.     They did
    not ascertain whether Ruiz-Mejia had an active driver's license
    or a license to carry a firearm.     They then set up surveillance
    outside the Gaelic Club on a Friday night and saw the car, and
    when a Hispanic-appearing male, the defendant, left the club,
    got in, and drove away, the police stopped the car.     They had
    2
    not entered the club.     They had not seen the defendant engage in
    drug sales or any other suspicious activity.
    Under Massachusetts law, we utilize the two-pronged
    Aguilar-Spinelli test1 to determine whether a tip can provide the
    reasonable suspicion that criminality is afoot necessary to
    allow an investigative stop.     The veracity prong requires the
    Commonwealth to demonstrate "that the source of the information
    was credible or the information reliable."     Commonwealth v.
    Depiero, 
    473 Mass. 450
    , 454 (2016).    The central issue in this
    case, as the court recognizes, is the veracity of the
    confidential informant.
    The court also recognizes, and I agree, that, as the motion
    judge also correctly concluded, the Commonwealth could have
    established the informant's veracity only by showing that the
    informant had been a tipster in the past, and not merely a
    controlled buyer.   This is because, while it is well established
    that an informant's history of providing tips leading to the
    seizure of narcotics can establish the informant's veracity, see
    Commonwealth v. Perez-Baez, 
    410 Mass. 43
    , 45 (1991), as we have
    held, one who merely participates in controlled buys is a person
    of "unknown reliability."     Commonwealth v. Carrasquiello, 
    45 Mass. App. Ct. 772
    , 776 (1998).     See 
    id.
     at 774-777
    1 See Aguilar v. Texas, 
    378 U.S. 108
     (1964); Spinelli v.
    United States, 
    393 U.S. 410
     (1969).
    3
    (distinguishing the veracity of tipsters from that of controlled
    buyers).   This is because while buying drugs on behalf of the
    police does provide them with information, it does not entail
    providing them with any information the police have not
    generated themselves.   See 
    ibid.
       See also Commonwealth v.
    Desper, 
    419 Mass. 163
    , 168 (1994) (describing the process of
    controlled buys).
    And, while corroboration of certain details of a tip can
    lead to a conclusion that the person who provided it was
    truthful, confirmation only of the publicly-knowable and not
    suspicious facts provided by the tipster that a person who
    drives a certain car goes to a particular club on Friday
    evenings is insufficient to demonstrate the veracity of the
    tipster's claim that the person also engages in unlawful

    , 20-21 (1990)
    ("[T]he quantity and quality of the details corroborated by the
    police were simply insufficient to establish any degree of
    suspicion that could be deemed reasonable.   The trooper was able
    to verify only the description of the automobile, the direction
    in which it was headed, and the race and gender of the occupants
    before making the stop. . . .   [T]he informant's reliability was
    only slightly enhanced by this corroboration because the police
    verified no predictive details that were not easily obtainable
    by an uninformed bystander. . . .   Significantly . . . these
    4
    defendants displayed no suspicious behavior that might have
    heightened police concern.   Anyone can telephone the police for
    any reason").
    In this case, the only evidence of the informant's past
    involvement with the police came from Sergeant William West's
    testimony.   On direct examination, he testified that, in the
    past, the informant had provided "information" that led to drug
    arrests and the seizure of money and narcotics.
    In cross-examination, though, the defendant's experienced
    counsel asked Sergeant West, "And if [an individual utilized by
    the Billerica police department to make controlled buys] had, in
    fact, made a series of purchases on behalf of the Billerica
    [p]olice [d]epartment, you could honestly say that that
    individual had provided you with information that if it did lead
    to arrest, to arrest and seizure, is that fair to say?"   The
    sergeant said, "Yes."   Counsel then asked, "In the past was [the
    informant in this case] able to make controlled buys for you
    when you did use him as an informant for the Billerica [p]olice
    [d]epartment?"   Again, the sergeant said, "Yes."
    The Commonwealth bears the burden of demonstrating the
    lawfulness of the seizure and thus in this case, in order to
    demonstrate the veracity of the tip, that the confidential
    informant had previously acted as a tipster and not merely as a
    controlled buyer.   Defense counsel's careful cross-examination
    5
    made clear that, according to Sergeant West himself, even if one
    had taken Sergeant West's direct testimony to mean that the
    informant had provided tips in the past, that was not
    necessarily its meaning.   While West's testimony left open the
    possibility that the confidential informant might have been a
    tipster as well as a controlled buyer, the officer's direct
    testimony did not mean that the informant was such a tipster.
    The Commonwealth could have clarified the matter on
    redirect by asking Sergeant West whether the informant had ever
    provided tips.   It declined to do so.   Perhaps this was because
    it knew that the confidential informant in fact was not a
    tipster; perhaps it was not.   But in either event, the
    Commonwealth, which, it bears repeating, has the burden here,
    left a record in which there was insufficient evidence to
    support the finding, necessary to the motion judge's conclusion
    that the search was lawful, that the confidential informant had
    previously been a tipster, not only a controlled buyer.2
    The Commonwealth recognized this below, and did not even
    argue before the judge that the evidence supported a finding
    that the confidential informant was a tipster.   Defense counsel
    2 The court suggests in a footnote that the facts that the
    informant called Sergeant West with information regarding the
    defendant's drug sales, and that he had noted the description of
    the car, suggests "at least a likelihood that this was not his
    first tip." But calling a police officer to tell him someone is
    dealing drugs at a particular place and describing his car
    hardly indicates that one has done so before.
    6
    argued:    "At no time did the sergeant ever say that this
    informant was a tipster. . . .      I didn't ask him.   My brother
    didn't ask him. . . .   [A]ll we know about this person, this
    informant" is that "[h]e has performed controlled buys
    successfully . . . .    We don't know whether he was ever a
    tipster.    [West] was never asked."
    The Commonwealth did not disagree, arguing only (and
    incorrectly) that any information leading to "an arrest and
    seizure of contraband substances was by itself sufficient to
    establish reliability," and that, coupled with the details that
    were corroborated, it was sufficient.3
    The court majority addresses the state of the record with
    respect to the confidential informant by saying first that we
    must defer to the motion judge's assessment of Sergeant West's
    credibility.   Of course we must.      But the issue is not whether
    Sergeant West is credible, nor did the judge say it was.4      The
    3 Even here, on appeal, the Commonwealth does not explain
    what supported the judge's finding, asserting without
    elaboration only that the "weight and credibility of testimony
    are functions of [the] motion judge, and factual findings will
    stand absent clear error."
    4 The support for the judge's finding that the informant had
    provided tips in the past was limited to quoting Sergeant West's
    testimony that the informant had more than once provided
    "information" leading to arrests and seizures of drugs and
    money, and drawing the following inadequately-supported
    inference therefrom: "I understand this testimony to mean that
    the CI supplied substantive information as well as helping with
    controlled buys, which he also did, and I so find."
    7
    issue is what Sergeant West said.     I assume he was perfectly
    credible.    His testimony, though, cannot support a finding that
    the confidential informant provided tips in the past.      It is
    silent on that question.
    The court majority then suggests that the "more
    important[]" reason we must affirm is that we must defer to the
    fact finder's choice between "two permissible views of the
    evidence."   Ante at     .   That statement of black letter law is
    of course true as well, but it is equally irrelevant.
    To illustrate the point:     If there were testimony that an
    event happened on a weekend, a judge could not infer solely on
    that basis that the day on which it happened was a Saturday
    rather than a Sunday.    That would not be a case in which one
    could draw one of two permissible inferences from the evidence
    in the record (i.e., that it happened on a Saturday or that it
    happened on a Sunday).     It would be one in which there was
    insufficient evidence in the record to support a conclusion on
    the matter in either direction.     The event might have happened
    on a Saturday.    Or it might have happened on a Sunday.    But
    there is no basis upon which a fact finder could, without more,
    determine which one.     And if it was one party's burden to prove
    the event happened on a Saturday, that party would have failed
    to meet its burden.
    8
    That is precisely this case.    Whatever one might have
    thought initially about Sergeant West's direct testimony, given
    his own clarification on cross-examination, it meant only that
    the confidential informant might have been a tipster (and a
    controlled buyer as well), or that he might have been only a
    controlled buyer.   But there was no evidence in the record to
    support the judge's conclusion that the informant was the former
    rather than the latter.   Choosing between two different possible
    factual scenarios, either of which might have happened, where
    there is no evidence in the record about which one actually did
    occur, is far different than choosing between two permissible
    views of the evidence in the record, and there would be little
    left of the rule of law if we eliminated that distinction.
    Because the Commonwealth did not provide sufficient
    evidence to support a positive finding about the veracity of the
    confidential informant, it failed to demonstrate the reasonable
    suspicion necessary for the initial stop of the defendant's
    vehicle.   While I have no quarrel with the rest of the
    majority's analysis, because all the evidence seized was fruit
    of that unlawful stop, it should have been suppressed.    With
    respect, I therefore dissent.
