    Before F LAUM, R OVNER, and SYKES, Circuit Judges.
    F LAUM, Circuit Judge. In July 2008, Chicago police officers
    pulled over a Suburban at the request of another Chicago
    police officer, who was a member of a Drug Enforcement
    Administration (“DEA”) task force. A subsequent
    warrantless search of the vehicle, in which defendant-
    appellant Aaron Williams was a passenger, revealed a
    brick of cocaine. The district court denied Williams’s
    motion to suppress the drug evidence on the grounds that
    the DEA task force had probable cause for the search,
    2                                              No. 10-1608
    which could be imputed to the officers under the collective
    knowledge doctrine. Williams entered a guilty plea to one
    count of possession with intent to distribute 500 grams
    or more of a substance containing cocaine, 
    21 U.S.C. § 841
    (a)(1), in which he preserved his right to challenge
    the suppression ruling. The district court sentenced
    Williams to 60 months of imprisonment. Williams appeals
    the denial of his motion to suppress.
    For the following reasons, we affirm.
    I. Background
    In the summer of 2008, the Drug Enforcement
    Administration (“DEA”) was investigating an alleged
    drug-trafficking organization. In connection with that
    investigation, a DEA-led task force used court-authorized
    wiretaps to intercept phone calls made and received by
    individuals suspected to be involved in the drug-traffick-
    ing ring. On July 15, 2008, the DEA intercepted a series of
    calls between Bernardo Solano, Filiberto Hinojosa, and
    Leobardo Barmbila that led them to believe that a drug
    transaction was going to occur at a suspected stash house
    located in the 2700 block of North Monitor Avenue in
    Chicago, Illinois. During one of those calls, Hinojosa
    informed Solano that “the car parts” had arrived at the
    “shop.” Agents conducted surveillance on the Monitor
    residence, and stopped an individual later identified as
    Solano after seeing him leave the house. Solano admitted
    that he had purchased two kilograms of cocaine at the
    Monitor residence. From photographs provided by DEA
    agents, Solano identified Hinojosa as the person from
    No. 10-1608                                              3
    whom he had purchased the cocaine, and Barmbila as the
    person who he believed had supplied the cocaine.
    The following day, the DEA intercepted additional phone
    calls between Hinojosa and Barmbila, in which they
    discussed meeting the “black guy” at the “shop on Moni-
    tor” later that day. Based on those calls, DEA agents
    decided to conduct surveillance on the Monitor residence
    at the anticipated time of the transaction, and to put
    officers from the Chicago Police Department (“CPD”) on
    standby to assist.
    Chicago police officer Daniel Gutierrez, a member of the
    task force, was responsible for coordinating the DEA’s
    efforts with the CPD. Prior to the anticipated transaction,
    Gutierrez met with a number of Chicago police officers,
    including officer Joseph Simon, and told them that a
    person would be coming to the Monitor residence to
    purchase narcotics. Gutierrez had not heard the inter-
    cepted phone calls himself, but he was in contact with the
    agents who had monitored the calls. Gutierrez requested
    that the officers position themselves in the area. He told
    them that he would provide them with information about
    the suspect vehicle, and that they should stop the vehicle
    after developing their own probable cause to do so.
    Members of the task force conducting surveillance on the
    Monitor residence saw Williams and another individual,
    Ennis Howard, arrive in a Chevy Suburban at approxi-
    mately 11:30 A.M . Howard and Williams parked the
    Suburban in an alley behind the Monitor residence and
    entered the backyard. Williams was carrying a brown
    shoebox. Approximately fifteen minutes later, agents saw
    4                                               No. 10-1608
    Howard and Williams leave the backyard carrying the
    brown shoebox, get in the Suburban, and drive away.
    Gutierrez, who was conducting surveillance near the
    Monitor residence, saw the Suburban drive away from the
    Monitor residence and turn onto Diversey Avenue.
    Gutierrez called Simon, gave him a description of the
    vehicle and the license plate, and informed him that the
    vehicle was heading eastbound on Diversey.
    Simon and his partner began following the Suburban and
    eventually stopped the vehicle. Simon instructed Howard
    and Williams to exit the vehicle. A pat-down search
    revealed two bags of marijuana in Williams’s pocket. A
    subsequent search of the Suburban by other officers who
    arrived on the scene led to the discovery of a brown
    shoebox in the back seat of the Suburban containing a brick
    of what was later confirmed to be a kilogram of cocaine.
    Williams was charged in an indictment with one count of
    possession with intent to distribute 500 grams or more of
    a substance containing cocaine. See 
    21 U.S.C. § 841
    (a)(1).
    On March 31, 2009, Williams filed a motion to suppress the
    evidence seized by police following the July 16, 2008 traffic
    stop. At a hearing on the motion, Simon testified that, after
    following the Suburban for a period of time without
    observing any traffic violations, he pulled alongside the
    vehicle. Simon testified that he could see that the
    passenger-side occupant was not wearing a seat belt, and
    that he stopped the Suburban based on that violation.
    While Illinois law requires drivers and (most) passengers
    of motor vehicles to wear seatbelts, 625 ILCS 5/12-603.1(a),
    a police officer “may not search or inspect a motor vehicle,
    No. 10-1608                                                  5
    its contents, the driver or a passenger solely because of” a
    driver or passenger’s failure to wear a seat belt, 
    id.
     at
    § 603.1(f); see also 725 ILCS 5/108-1(3). Simon testified that,
    at the time of the stop, he was aware that the seat belt
    violation would not justify a search of the vehicle or its
    occupants. According to Simon, when he approached the
    vehicle, he saw “crumbs” of marijuana on the center
    console and two cigar-like objects in the open ashtray.
    Based on what he believed to be marijuana in plain view,
    Simon ordered the occupants to exit the vehicle.
    Williams also testified at the suppression hearing. He
    acknowledged that there were two unsmoked marijuana
    cigars in the ashtray, but stated that he had closed the
    ashtray when the vehicle was pulled over. He also testified
    that there were no “crumbs” or any other marijuana on the
    center console.
    The district court concluded that Simon’s testimony was
    not credible. In reaching that conclusion, the district court
    relied on Simon’s manner of testifying, as well as on
    Simon’s professed strategy for effecting the desired search,
    which the court concluded made “little sense.” According
    to Simon, he decided to pull the Suburban over for a
    violation he knew did not provide him with the probable
    cause he needed to search the vehicle. Then, if Simon is
    believed, he fortuitously saw marijuana in plain view
    because—contrary to Williams’s testimony—Howard and
    Williams, knowing they had a kilogram of cocaine in the
    back seat, left the ashtray containing marijuana open for
    two approaching officers to see. Finding Simon not to be
    credible, the district court determined that the search of the
    6                                                       No. 10-1608
    Suburban was not supported by the seat belt violation the
    officers testified that they observed, or the marijuana the
    officers testified they observed in plain view in the Subur-
    ban. The district court nevertheless denied Williams’s
    motion to suppress, concluding that the DEA’s wiretap
    investigation and surveillance evidence gave the CPD
    officers probable cause to search the Suburban under the
    collective knowledge doctrine.
    On December 4, 2009, Williams entered into a conditional
    guilty plea, reserving the right to appeal the denial of his
    motion to suppress. On March 2, 2010, the district court
    sentenced Williams to 60 months of imprisonment. This
    appeal followed.
    II. Discussion
    On appeal, Williams challenges the denial of his motion
    to suppress the evidence found during the warrantless
    search of the vehicle.1 In reviewing a district court’s denial
    1
    We note that while “the provider and driver of the car” has “a
    reasonable expectation of privacy in it[,] . . . a mere passenger”
    does not. United States v. Price, 
    54 F.3d 342
    , 345-46 (7th Cir. 1995).
    We have found nothing in the record to suggest that Wil-
    liams—the passenger—owned the Suburban in which he and
    Howard were stopped. However, the government has not
    argued that Williams lacks standing to challenge the search of
    the vehicle. See id.; Rakas v. Illinois, 
    439 U.S. 128
     (1978) (illegal
    search of vehicle does not infringe passengers’ Fourth Amend-
    ment rights, and passengers lack standing to challenge the
    (continued...)
    No. 10-1608                                                     7
    of a motion to suppress evidence, we review conclusions of
    law de novo and findings of fact for clear error. United
    States v. Booker, 
    612 F.3d 596
    , 599 (7th Cir. 2010). Probable
    cause determinations are mixed questions of law and fact
    that we review de novo. 
    Id.
    Warrantless searches are considered per se unreasonable
    under the Fourth Amendment unless one of a few specifi-
    cally established and well-delineated exceptions applies.
    Arizona v. Gant, ___ U.S. ___, 
    129 S.Ct. 1710
    , 1716 (2009).
    One such exception to the warrant requirement is the
    automobile exception, which allows law enforcement to
    conduct a warrantless search of a vehicle if there is proba-
    ble cause to believe the vehicle contains contraband or
    evidence of a crime. See United States v. Zahursky, 
    580 F.3d 515
    , 521 (7th Cir. 2009); Carroll v. United States, 
    267 U.S. 132
    ,
    153-56 (1925). When probable cause exists to search a
    vehicle, law enforcement agents are permitted to search all
    parts of the vehicle in which contraband or evidence could
    be concealed, including closed compartments, containers,
    packages, and trunks. United States v. Scott, 
    516 F.3d 587
    ,
    589 (7th Cir. 2008); United States v. Ross, 
    456 U.S. 798
    , 823-24
    (1982).
    Here, our inquiry is two-fold. First, we must decide
    whether the DEA task force had enough information to
    1
    (...continued)
    search). Therefore, the argument is waived and we need not
    consider it. Price, 
    54 F.3d at 346
     (the principle of “standing” is
    “rooted in the substantive law of the Fourth Amendment and
    not Article III,” and consequently can be waived).
    8                                               No. 10-1608
    support a finding of probable cause to search the vehicle.
    Second, if so, we must determine whether that information
    can be imputed to the officers who conducted the stop and
    search under the collective knowledge doctrine.
    A. Probable Cause
    Probable cause to search exists where, based on the
    known facts and circumstances, a reasonably prudent
    person would believe that contraband or evidence of a
    crime will be found in the place to be searched. See
    Zahursky, 
    580 F.3d at 521
    ; Scott, 
    516 F.3d at 589
    . Here, the
    question is whether there was “a fair probability” that
    contraband or evidence of a crime would be found in the
    Suburban; absolute certainty of such a discovery is not
    required. Zahursky, 
    580 F.3d at 521
    . The determination
    whether suspicious circumstances rise to the level of
    probable cause is a common-sense judgment, and officers
    are entitled to draw reasonable inferences based on their
    training and experience in making that determination.
    United States v. Reed, 
    443 F.3d 600
    , 603 (7th Cir. 2006).
    We conclude that the facts known to the DEA task force
    supported a search of the vehicle. On July 16, 2008, agents
    intercepted calls between Hinojosa and Barmbila discuss-
    ing a meeting with “the black guy” at “the shop” on
    Monitor. Agents then observed Howard and Williams
    arrive at the Monitor residence, enter the backyard carry-
    ing a shoebox, and exit shortly thereafter carrying the same
    shoebox. The day before, agents had intercepted calls
    between Hinojosa and Barmbila, and between Hinojosa
    and Solano, during which they arranged a meeting at “the
    No. 10-1608                                                 9
    shop.” Later on July 15th, agents had observed Solano
    leaving the Monitor residence carrying a package, which
    Solano subsequently admitted contained two kilograms of
    cocaine that he had purchased from Hinojosa and Barmbila
    at the Monitor residence. Taken as a whole, these facts
    justified the agents’ belief that Howard and Williams
    purchased drugs at the Monitor residence, and that a
    search of the Suburban would uncover those drugs.
    Williams argues that agents could not reasonably have
    believed that he and Howard went to the Monitor resi-
    dence to buy drugs because the calls intercepted on July
    16th did not discuss any particular drug, weight, or dollar
    amount—even in code. According to Williams, the calls
    suggest only that a meeting was to take place, not necessar-
    ily a drug transaction. As we have said before, “a finding
    of probable cause does not require evidence sufficient to
    support a conviction, nor even evidence demonstrating
    that it is more likely than not that the suspect committed a
    crime.” United States v. Funches, 
    327 F.3d 582
    , 587 (7th Cir.
    2003). All that is required is a fair probability of discover-
    ing contraband. Here, the totality of the facts and circum-
    stances—that Williams and Howard met Hinojosa and
    Barmbila (suspected drug dealers) at the Monitor residence
    (a suspected stash house), where agents knew Hinojosa
    and Barmbila had carried out a drug transaction as recently
    as the day before, and that Williams and Howard left that
    meeting carrying a shoebox (in which they could conceal
    drugs)—were sufficient to create probable cause even
    absent such details in the calls themselves. Moreover, that
    Williams and Howard’s conduct on July 16th “taken in
    isolation, . . . might be innocently explained away” does
    10                                                No. 10-1608
    not preclude a finding of probable cause. United States v.
    Scott, 
    19 F.3d 1238
    , 1242 (7th Cir. 1994) (“it is of no moment
    that most of [defendant’s] conduct . . . may have been
    unrelated to drug activity” where the officers, “view[ing]
    [the] conduct as a whole” and in light of their training and
    experience, concluded that defendant was engaged in drug
    trafficking). Here, the facts and circumstances surrounding
    the meeting were sufficient to justify the officers’ belief,
    based on their experience in policing narcotics transactions,
    that a drug transaction had occurred.
    B. Collective Knowledge Doctrine
    Having determined that the DEA task force had probable
    cause to search the vehicle, we consider whether the
    information known to the task force can be imputed to
    Simon under the collective knowledge doctrine. The
    collective knowledge doctrine permits an officer to stop,
    search, or arrest a suspect at the direction of another officer
    or police agency, even if the officer himself does not have
    firsthand knowledge of facts that amount to the necessary
    level of suspicion to permit the given action. See United
    States v. Hensley, 
    469 U.S. 221
    , 232-33 (1985). There is no
    Fourth Amendment violation if the knowledge of the
    officer directing the stop, search, or arrest—or the collec-
    tive knowledge of the agency for which he works—is
    sufficient to constitute probable cause. United States v.
    Harris, 
    585 F.3d 394
    , 400 (7th Cir. 2009). In order for the
    collective knowledge doctrine to apply, (1) the officer
    taking the action must act in objective reliance on the
    information received, (2) the officer providing the informa-
    No. 10-1608                                                 11
    tion—or the agency for which he works—must have facts
    supporting the level of suspicion required, and (3) the stop
    must be no more intrusive than would have been permissi-
    ble for the officer requesting it. United States v. Nafzger,
    
    974 F.2d 906
    , 911 (7th Cir. 1992).
    We have applied the collective knowledge doctrine
    where, as is the case here, DEA agents asked local law
    enforcement officers to stop a specifically-identified
    vehicle, and the local officers had no knowledge of the facts
    underlying the DEA’s probable cause. For example, in
    United States v. Rodriguez, 
    831 F.2d 162
    , 166 (7th Cir. 1987),
    the DEA requested that Illinois State Police make a
    “routine traffic stop” of an individual the DEA believed
    was involved in drug-trafficking activities for the purpose
    of identifying the driver. The officer who made the stop
    knew nothing about the factual basis for the DEA’s suspi-
    cion, other than that the DEA was coordinating a large
    investigation with local agencies. 
    Id. at 165-66
    . Based on
    the facts of that case, which involved an admittedly
    “skeletal” request for assistance, we concluded that the
    “state trooper was . . . acting as an extension or agent of the
    DEA agent and she could act on the DEA agent’s suspi-
    cions.” 
    Id.
     In United States v. Celio, 
    945 F.2d 180
    , 183
    (7th Cir. 1991), Illinois State Police stopped and searched
    a vehicle at the request of the DEA, based solely “on the
    bald assertion by the federal agents that they suspected
    drug trafficking.” As in Rodriguez, “the automobile to be
    stopped with its occupant was pointed out specifically by
    the requesting officer, and the [detaining] officer knew the
    requesting officer was coordinating a large investigation
    with local agencies.” 
    Id. at 184
     (quoting Rodriguez, 
    831 F.2d 12
                                                   No. 10-1608
    at 166). We concluded that the search was supported by
    probable cause because the DEA’s collective knowledge
    could be imputed to the officers under the collective
    knowledge doctrine. 
    Id.
    The facts here are analogous to those at issue in Rodriguez
    and Celio. Gutierrez specifically identified the Suburban
    and its occupants for Simon, who was aware of the ongo-
    ing DEA investigation. In fact, Simon knew more about the
    underlying facts than did the local officers in Rodriguez and
    Celio, as he knew that the vehicle was leaving a suspected
    drug transaction.
    Williams attempts to distance his case from Rodriguez
    and Celio based on Gutierrez’s instruction that Simon
    develop his own probable cause to stop and search the
    Suburban. According to Williams, that statement pre-
    cluded Simon from relying on the DEA’s knowledge, and
    therefore Simon could not have been acting in objective
    reliance on the information he received from Gutierrez, as
    is required for the application of the collective knowledge
    doctrine. We disagree with Williams’s characterization of
    the instruction. Gutierrez did not forbid Simon from
    relying on the information collected by the DEA task force.
    Rather, Gutierrez sought to conceal the existence of the
    DEA investigation and wire taps from Williams and
    Howard. That effort has no impact on the fact that the
    DEA agents had probable cause, on which Simon was
    entitled to rely.
    Other appeals courts similarly have concluded that the
    application of the collective knowledge doctrine is unaf-
    fected by an officer’s use of a cover story to disguise a stop
    No. 10-1608                                                13
    as a mere traffic stop. See United States v. Chavez, 
    534 F.3d 1338
    , 1341-42 (10th Cir. 2008) (where officer stopped
    suspect at DEA’s request, the fact that the officer pretended
    that the stop was for a failure to turn on headlights in order
    to conceal a confidential informant’s identity and protect
    the integrity of the DEA investigation did not preclude the
    application of the collective knowledge doctrine);
    United States v. Ramirez, 
    473 F.3d 1026
    , 1038 (9th Cir. 2007)
    (Kozinski, J., concurring) (“disguising the stop as a ‘traffic
    stop’ was a valid law enforcement tactic calculated to
    ensure an officer’s safety . . . [and] did not change the
    nature of the stop,” or the fact that the stop was made at
    the direction of an officer who had probable cause, such
    that the collective knowledge doctrine applies). Moreover,
    the Fifth and Tenth Circuits have considered instructions
    like the one Gutierrez gave Simon, and concluded that such
    an instruction does not bar the application of the collective
    knowledge doctrine.
    In United States v. Ibarra-Sanchez, 
    199 F.3d 753
     (5th Cir.
    1999), a DEA agent instructed the local police dispatcher to
    issue a radio bulletin stating that a DEA agent needed
    assistance in stopping a van suspected to be transporting
    drugs or weapons, and that the officers should form their
    own reasonable suspicion before stopping the van. 
    Id. at 757
    . The DEA agent asked local authorities to make the
    stop to avoid revealing the existence of the DEA investiga-
    tion. 
    Id.
     at 757 n.1. The dispatcher issued the bulletin, but
    did not include the instruction that officers form their own
    reasonable suspicion. 
    Id. at 757
    . After hearing the bulletin,
    a police officer and SWAT team stopped the van. 199 F.3d
    at 757. The Fifth Circuit held that the stop was constitu-
    14                                               No. 10-1608
    tional because the DEA agent’s knowledge could be
    imputed to the officers under the collective knowledge
    doctrine. Id. at 759-60. The court noted that the dispatcher’s
    “failure to relate [the agent’s] instruction that the [local
    police] officers form their own reasonable suspicion before
    stopping the van” was “irrelevant.” Id. at 760 n.6. The court
    found the defendants’ argument to the contrary to be
    “immaterial . . . because under the ‘collective knowledge’
    doctrine, the [local] officers did not need to form their own
    suspicion.” Id. As Williams points out, the message about
    developing independent suspicion was not relayed to the
    detaining officers in Ibarra-Sanchez, while Gutierrez’s
    instruction was communicated to Simon here. But the Fifth
    Circuit’s description of the dispatcher’s failure to pass on
    the instruction as “irrelevant,” and its characterization of
    the defendants’ argument that the failure somehow was
    relevant as “immaterial,” indicate that the court would
    have concluded that the collective knowledge doctrine
    applied regardless of whether the instruction was included
    in the bulletin. Id.
    Chavez is even more factually analogous to the instant
    case. There, the requesting DEA agent instructed the state
    police officer tasked with stopping a vehicle suspected to
    be transporting cocaine to develop his own probable cause
    for stopping the vehicle. 
    534 F.3d at 1341
    . The Tenth Circuit
    found that the stop was proper under the collective
    knowledge doctrine because the DEA agent who requested
    the stop had probable cause. 
    Id. at 1348
    . The court appar-
    ently found the instruction that the officer develop his own
    probable cause to be of no consequence to the collective
    knowledge inquiry, as it did not address the instruction,
    No. 10-1608                                                 15
    except to note that the officer’s use of a cover story to
    conceal the reason for the stop “was a valid law enforce-
    ment tactic.”

     (quoting Ramirez, 
    473 F.3d at 1038
    (Kozinski, J., concurring)).
    Williams also contends that the collective knowledge
    doctrine does not apply because Simon testified that he did
    not rely on the information he received from Gutierrez to
    justify the search. But Simon’s subjective reasons for
    making the stop and initiating the search are irrelevant, as
    “[s]ubjective intentions play no role in the ordinary,
    probable-cause Fourth Amendment analysis.” Whren v.
    United States, 
    517 U.S. 806
    , 813 (1996) (case law “foreclose[s]
    any argument that the constitutional reasonableness of
    traffic stops depends on the actual motivations of the
    individual officers involved”); see also Florida v. Royer, 
    460 U.S. 491
    , 507 (1983) (the fact that officers acted on one
    rationale in conducting a search does “not foreclose the
    [government] from justifying [the search] by proving
    probable cause”). Therefore, Simon’s motivations for the
    stop and search do not affect the collective knowledge
    doctrine analysis.
    Our decision is consistent with the Ninth Circuit’s
    opinion in Ramirez. In Ramirez, a police sergeant requested
    that a uniformed officer make a “traffic stop” of a car
    suspected to have been involved in a drug transaction. 
    473 F.3d at 1029
    . A uniformed officer made the requested
    traffic stop when he observed the car straddling two lanes.
    
    Id.
     The defendants argued that the stop was invalid
    because lane-straddling is not illegal. 
    Id. at 1030
    . Based on
    Whren, the Ninth Circuit concluded that neither the fact
    16                                               No. 10-1608
    that the officer “was directed to make a traffic stop,” nor
    the fact that he may not have had “valid grounds to make
    the traffic stop because of lane-straddling,” was relevant
    because the officer had probable cause based on the
    collective knowledge doctrine. 
    Id. at 1030
    .
    Williams maintains that even if the collective knowledge
    doctrine applies, only Gutierrez’s knowledge—and not that
    of the entire DEA task force—can be imputed to Simon.
    Williams asserts two arguments in support of that position.
    First, he contends that the knowledge gleaned from the
    wiretaps cannot be imputed to Simon because Gutierrez
    did not listen to the wiretap conversations. Second, he
    argues that the knowledge of the DEA agents (i.e., the
    substance of the wire tap conversations) cannot be imputed
    to Gutierrez because he worked for a different agency, the
    CPD. We address each argument in turn.
    As noted above, Gutierrez was a member of the DEA-led
    task force. He testified that, prior to briefing Simon and the
    other CPD officers, he became aware that calls had been
    intercepted indicating that there was going to be a narcot-
    ics sale at the Monitor residence. Gutierrez was in radio
    contact with members of the surveillance team who
    informed him that they had observed Howard and Wil-
    liams enter and leave the Monitor residence carrying the
    shoebox. Therefore, based on communications with other
    task force members, Gutierrez had indirect knowledge of
    the facts supporting probable cause.
    We previously have held that whether the requesting
    officer had direct knowledge of the facts supporting his
    suspicion is “inconsequential” where the agents in posses-
    No. 10-1608                                                17
    sion of the knowledge and the requesting agents are “part
    of a coordinated investigation” and are in communication.
    Nafzger, 
    974 F.2d at 914
    . The knowledge of a team of
    officers “work[ing] together closely in monitoring [a] drug
    transaction as it unfold[s] . . . ‘may be mutually imputed’ ”
    even the absence of “ ’express testimony that the specific or
    detailed information creating the justification for the stop
    was conveyed.’ ” United States v. Parra, 
    402 F.3d 752
    , 766
    (7th Cir. 2005) (quoting Nafzger, 
    974 F.2d at 911
    ). Therefore,
    knowledge of the information contained in the intercepted
    phone calls can be imputed to Gutierrez based on his role
    in the task force’s investigation.
    Williams’s second objection also fails to carry the
    day, although we recognize that the language of some of
    our precedents may be misleading. We have said that
    knowledge may be imputed to an officer “so long as the
    knowledge of the officer directing the [challenged action],
    or the collective knowledge of the agency he works for, is
    sufficient to constitute probable cause.” United States v.
    Valencia, 
    913 F.2d 378
    , 383 (7th Cir. 1990) (emphasis added).
    That language was designed to recognize that the knowl-
    edge of other officers may be imputed to the requesting
    officer, so long as the officers are in close communication
    with one another. Here, Gutierrez was assigned to the DEA
    task force and worked closely with DEA agents on the
    drug trafficking investigation. That he carried a badge
    issued by the CPD, not the DEA, does not preclude the
    application of the collective knowledge doctrine. Therefore,
    the district court correctly imputed the DEA task force’s
    knowledge to Gutierrez and Simon.

    III. Conclusion
    For the foregoing reasons, we AFFIRM the district court’s
    judgment.
