Ulice Askew challenges the sufficiency of the evidence supporting his conviction under 21 U.S.C. § 846 for conspiracy to possess with intent to distribute PCP. He argues that the only credible evidence against him established one PCP spot purchase amounting to a buyer-seller relationship only, not a conspiracy. Relatedly, Askew argues that the district judge committed plain error by failing to supply the jury with a buyer-seller instruction. He also asserts that the judge failed to answer appropriately the jury’s questions during deliberations about the conspiracy count. His final ground for appeal alleges that the judge committed plain error when she failed to suppress evidence obtained through an unconstitutional stop that led to his arrest. For the reasons discussed below, we affirm.
I. History
Christine Williams worked for Napoleon “Pokey” Moore as a PCP distributor beginning in June 1999. Her relationship with Moore ended in December 2001, when she was arrested and agreed to cooperate with the FBI.
According to Williams, Askew was one of the customers to whom she regularly *499 sold PCP. Williams testified that her business relationship with Askew began in the summer of 2000, after Moore directed her to sell PCP to Askew to “help him get back on his feet.” 1 Moore set the prices for the PCP sold, often allowing Askew to pay a portion of the price, with the remainder to be paid at the next buy. For a time, Moore also charged Askew less for PCP than he charged other customers. Williams believed Askew and Moore to be “best friends.”
Williams sold PCP to Askew almost weekly between the summer of 2000 and her arrest in December 2001. Askew would contact either Moore or Williams to let them know when he needed the drugs. Williams testified that Askew purchased a total of sixteen ounces (453 grams) to twenty ounces (566 grams) of PCP each month and that she would typically make deliveries to his home on South Millard Avenue in Chicago. According to the expert witness presented by the government, sixteen ounces, or one pint, of PCP amounted to 10,000 to 20,000 individual doses.
On January 4, 2002, after her arrest and while in FBI custody, Williams received a call from Askew. He introduced himself as “Pokey[’s] guy” from “off Millard.” When she asked him what he was “tryin’ to do,” he responded, “[A] whole one.” Williams then said, “The whole one? ... [Y]ou usually get the half. What you tal-kin’ about a whole one?” Askew responded, “You know[,] the two fours,” which Williams understood to mean eight ounces of PCP. In another call that same day, Askew told Williams that Moore set the price of the purchase at a “stack,” or $1000.
At the FBI’s direction, Williams called Askew on January 9, 2002, and proposed that the buy take place at the Homan Square Theater, located in a busy strip mall. Williams told Askew that Moore said she could sell him a “pop” (sixteen ounces of PCP) for $1300, which was a better price than $1000 for an “eight” (eight ounces of PCP). Askew told Williams that all he could come up with was $1100. As had been done in the past, Williams proposed that he pay the $1100 up front and supply the remaining $200 later. The two agreed to meet at 11:00 A.M. that same day. Askew informed Williams that she could find him in a white Cadillac.
At 11:05 A.M., Williams called Askew to check on his status. Askew stated that he had already been to the meeting place and had just left. Williams, who was actually in the Dirksen Federal Building with her FBI handlers in downtown Chicago, represented that she was just arriving in her car and asked him to turn around and meet her, which she said should take “two or three minutes.” Askew agreed and again indicated he could be recognized by the white Cadillac. Shortly thereafter, Williams again called Askew to tell him she had arrived and to determine his whereabouts. Askew stated that he was in the parking lot and described his location — “by that little red truck. Where that lady walkin [sic].” When Williams protested that she could not see him, he told her he was pulling out and was “in front of the theater now” but in “another car.” The call then cut off. All of these calls, beginning with the January 4, 2002, contact and others, were recorded and played for the jury at trial.
*500 Unbeknownst to Askew, FBI agents and Chicago police were positioned outside of the Homan Square Theater in unmarked cars. The agents sitting with Williams four miles away relayed, by radio, the content of her conversations with Askew to the law enforcement officers attempting to perform the arrest. The officers correctly identified a silver Hyundai Accent as the car carrying Askew based on the information provided by Williams through her handlers and also due to the car’s suspicious maneuvers — it was circling the lot as if its passengers were looking for someone. The agents blocked the vehicle with theirs and, with guns drawn, removed the occupants. Once Askew identified himself, they placed him under arrest and conducted a safety search. The agents found $1189 in cash.
While in custody, Askew signed a confession stating that in October 2001 he purchased one ounce (28 grams) of PCP from Williams for $200 and resold it for $300. He also admitted to his unsuccessful attempts to purchase more PCP from Williams in November 2001 and to his intent to buy sixteen ounces of PCP from Williams the day of his arrest.
At trial, the government’s evidence consisted primarily of Williams’s testimony, Askew’s confession, a pen register showing that Askew called Williams eighteen times between September 2001 and December 2001, and the recorded phone calls between Williams and Askew. Askew testified in his own defense and stated that he never, at'any time, purchased or intended to purchase PCP from Williams. Rather, he claimed that he planned to buy stereo speakers (his brother had previously testified the speakers were called “pops”) from Williams the day of his arrest, which were to be used to help promote his brother’s rap CD. He told the jury that he met Williams through Moore, but that Moore was a casual acquaintance that he had spoken to only three times — once around 1989 at an album release party, another time when he ran into him at a mall about twelve years later in 2001, and again sometime in late 2001. During the mall conversation, according to Askew, Moore put him in touch with Williams because her nephew was interested in the rap music industry. During the third conversation, Askew said he and Moore discussed the speakers Askew wanted to buy and that they worked out a package deal for the purchase. Askew testified that he had only spoken to Williams about five times in his life, and that she had never been to his house. He also disavowed his written confession, contending that he never even read it — he signed it only because he was scared and was told that the confession merely indicated his willingness to cooperate with the FBI.
The jury returned a verdict of guilty on all three counts charged. The verdict form for Count I (the conspiracy count and the only count at issue here) asked the jury to determine the amount of PCP attributable to Askew: one kilogram or more; 100 grams but less than one kilogram; or less than 100 grams. The jury chose the third option — less than 100 grams.
At sentencing, the district judge determined that 8,000 to 10,000 grams (eight to ten kilograms) of PCP was attributable to Askew on Count I. The judge also determined that Askew lied at trial about his involvement with the PCP conspiracy and gave him a two-level enhancement for obstruction of justice. The district court sentenced him to 210 months’ imprisonment on the conspiracy count, to be served concurrently with the sentences rendered on the other two counts of the indictment.
II. Analysis
A. Sufficiency of the Evidence
Askew challenges the sufficiency of the evidence supporting his conviction on *501 the indictment’s conspiracy count. His sole argument relies on the jury’s decision, in rendering its verdict, to attribute less than 100 grams of PCP to him. He reasons that the jury, who heard Williams testify to selling thousands of grams to Askew over a year-and-a-half period, must have completely discounted her witness testimony and accepted as true Askew’s confession that he purchased one ounce (28 grams) of PCP. Otherwise, Askew argues, the jury would have attributed far more PCP to Askew than it did. Based on that premise, Askew asserts that we should follow what he believes is the jury’s lead and review the record sanitized of Williams’s testimony. The remaining evidence, Askew posits, establishes not a conspiracy, but rather, at most, a buyer-seller relationship premised on spot purchases.
Because Askew’s sufficiency of the evidence appeal hinges on our treatment of Williams’s trial testimony, we must first determine whether, as Askew suggests, we should disregard it based on the jury’s verdict. Askew’s issue is somewhat unique: most defendants challenging their convictions because of verdict inconsistencies do so because they were acquitted on some counts that would seem to require acquittal on others of which they were found guilty,
e.g., United States v. Conn,
Regardless of how the apparent inconsistency in a jury’s determination presents itself, it is well established that “[i]n-consistent verdicts in a criminal case are not a basis for reversal of a conviction or the granting of a new trial.”
United States v. Reyes,
*502
When evaluating a sufficiency of the evidence challenge, we view all the evidence and draw all reasonable inferences in the light most favorable to the prosecution — a rigorous standard.
See United States v. Hicks,
Conspicuously, Askew does not make the alternative argument that even considering Williams’s testimony, the jury did not have sufficient evidence to convict on the conspiracy count. Because Askew does not challenge his conviction based on the record as a whole, but rather relies on a trial transcript figuratively excised of Williams’s testimony, we could end our discussion of the sufficiency issue here. Yet, in the interest of completeness, we note that our review of the record, including Williams’s testimony, satisfies us that the government presented the jury with sufficient evidence to establish Askew engaged in a conspiracy with Williams and Moore, not a mere buyer-seller relationship.
For Askew’s conspiracy conviction to stand, the government needed to convince the jury that “(1) two or more people agreed to commit an unlawful act and (2) the defendant knowingly and intentionally joined in the agreement.”
United States v. Gardner,
Here, Williams testified that she sold Askew PCP on Moore’s behalf almost weekly for a year and a half, resulting in the exchange of thousands of grams of drugs. The transactions were regulated by Moore, sometimes at below-average prices or volume discounts, and sometimes paid in part by Askew, with the rest owing at the next purchase. From this and other evidence — including the phone recordings reflecting Askew’s familiar relationship with Williams and Moore, the pen register revealing his eighteen calls to Williams in a two-month period, Askew’s close friendship with Moore that prompted him to help Askew “get back on his feet” after his financial woes, and Askew’s signed confession admitting to at least one consummated PCP deal — a rational trier of fact could find that Askew and Williams engaged in more than a buyer-seller relationship. Indeed, a jury could conclude beyond a reasonable doubt that an agreement to distribute PCP existed among Moore, Williams, and Askew and that Askew willingly and intentionally joined in the agreement.
B. Buyer-Seller Instruction
In line with his theory that the evidence established, at most, a buyer-seller relationship, Askew challenges the district judge’s failure sua sponte to supply the jury with an instruction (a “buyer-seller instruction”) explaining that repeated drug buys alone do not establish a conspiracy. Because Askew at no time requested a buyer-seller instruction or objected to its omission, we review the judge’s failure to include such an instruc
*503
tion for plain error.
United States v. Gee,
Our finding above that the jury had sufficient evidence to convict Askew on the conspiracy count does not automatically negate his claim that the judge committed plain error in failing to provide the jury with a buyer-seller instruction.
See, e.g., Gee,
Askew argues that"- the district court committed plain error in failing to realize that the evidence in this case necessitated a buyer-seller instruction to ensure that the jury understood it could not convict on the conspiracy count solely on the basis of repeated drug buys. In evaluating his claim, we note that “[ejach drug conspiracy case must be analyzed according to its specific facts to determine whether a buyer-seller instruction is appropriate.”
Douglas,
We first examine the evidence Askew offered at trial. It is undisputed that Askew did not advance a buyer-seller defense during trial. Instead, Askew’s strategy was to deny any involvement whatsoever *504 with illegal drugs. When he testified in his own defense, he claimed to have been introduced to Williams by Moore, whom he barely knew, because Williams’s nephew was interested in the rap music industry. He swore he never purchased or intended to purchase PCP from Williams, despite strong evidence suggesting otherwise, including: his signed confession admitting actual and intended purchases, the recorded phone conversations with Williams in which he made obvious attempts to purchase something (he says stereo speakers, she says PCP), and his arrest at the Ho-man Square rendezvous point carrying nearly $1200 in cash — enough to purchase the sixteen ounces of PCP offered by Williams for $1100 down with $200 owing.
Because Askew did not advance a buyer-seller theory of defense, his case is distinguishable from
Mims
and
Thomas,
two cases in which we reversed convictions based on missing or erroneous buyer-seller instructions. In both
Mims
and
Thomas,
the defendants’ theories at trial were that they were drug dealers/buyers, not drug conspirators.
See Mims,
Although Askew’s choice not to adopt a buyer-seller defense cuts in favor of finding no error in the district judge’s decision not to give the instruction, we must still review the evidence presented by the government to determine whether it was such that a jury could confuse a buyer-seller relationship with a conspiratorial one. For example, in
Gee,
we determined that the district court committed plain error when it failed to give the buyer-seller instruction sua sponte because the court had explicitly recognized that the conspiracy evidence against the defendants was weak.
No similar reservations were expressed by the district judge here, and rightly so, in light of the evidence presented at trial. As already noted, Williams testified to almost weekly sales of large quantities of PCP over a year-and-a-half period, during which time she, at Moore’s behest, regularly “fronted” Askew portions of the purchase. Moore agreed to let Williams sell him large quantities of PCP at wholesale prices so that Askew “could get back on his feet.” The logical inference to be drawn from this evidence was that all three agreed that Askew would purchase drugs from Moore through Williams so that Askew could redistribute it at a profit. This enabled Askew to pay off the amounts fronted to him and “get back on his feet”; the arrangement also provided a steady demand for Moore’s product. Such facts indicate a conspiracy, not a simple buyer-seller relationship. The strength of the government’s ease, combined with Askew’s
*505
choice not to present or argue any evidence tending to show he was involved in a buyer-seller relationship only, leads us to conclude that there was no clear error in not sua sponte giving a buyer-seller instruction.
See Baker,
Moreover, considering the relative strength of the evidence against Askew, we do not believe giving the instruction would have changed the outcome of the trial, as required under plain error review. The absence of that instruction, therefore, did not affect Askew’s substantial rights and does not warrant reversal.
C. Judge’s Response to Jury Questions
Askew also argues that the court-, in response to written questions forwarded by the jury during deliberations, failed properly to supplement the jury instructions and make it clear that events taking place after Williams agreed to cooperate with the government could not be considered part of the conspiracy agreement.
2
But Askew has waived any such objections because he explicitly agreed to the proposed response to the jury’s first set of questions and, as to the final questions posed by the jury, he actually suggested the response provided by the court.
See United States v. Lakich,
As reflected by the trial transcript, the jury first asked the following questions, among others:
[I]n considering the quantity of drugs involved in an alleged conspiracy, are we to consider evidence of transactions pri- or to the Jan. 9 arrest of Askew?
* * * * * 5l:
The jury wants to know if it should consider evidence up to and including the events of Jan. 9 in reaching a conclusion about the count one conspiracy, or does count one only deal with evidence prior to those events?
The judge consulted with the attorneys about the appropriate response. During that conference, Askew’s attorney stressed, “[M]y position is you should simply say to read the indictment and the instructions. I think you are getting into a place where you are telling them what to do other than just read the instructions and read the indictment, and I think that’s *506 the Court putting itself in the process.” (Tr. at 361.) After further discussion, the judge stated: “I suppose one other thing we can say is[,] ‘As to your other questions, you may consider whatever evidence you think is appropriate.’ ” (Tr. at 361.) The government agreed. Askew’s attorney stated, “All right,” to which the judge responded, “That would be alright?” Askew’s attorney answered, “Yes.” (Tr. at 362.) The judge then wrote the jury with the following response: “Thank you for your notes.... With regard to your remaining questions, you may consider whatever evidence you think is appropriate.”
The final questions asked by the jury were as follows:
Does count one conspiracy charge apply only to the period of “beginning in or about 2000 and continuing on or about Dec. 16, 2000” as outlined in the indictment?
In deciding whether the defendant is guilty of count 1, should the jury consider the events and evidence after Dec. 16 — or should the jury consider events and evidence only up to Dec. 16 and not beyond? [emphasis in original]
Askew’s attorney suggested the following response: “Just reread the conspiracy instruction. You should tell them that.” The judge responded, “Okay,” (Tr. at 370), and delivered the following message to the jury: “In response to your question, please reread the conspiracy instruction in your jury instructions.”
Considering his conduct during the conferences with the judge discussing the appropriate response to the jury’s questions, Askew has no basis for appeal now. 3
D. Evidence Suppression
Askew argues that the $1189 seized after he was stopped and searched by the FBI outside the Homan Street Theater and the confession procured after his arrest should have been suppressed because the initial stop was a seizure that violated the Fourth Amendment. He states that the stop, in which FBI agents blocked his vehicle with theirs and ordered him out of the car with weapons drawn, constituted a full arrest unsupported by probable cause. In the alternative, he argues that if the actions of the FBI can be characterized as a
Terry
investigative stop,
see Terry v. Ohio,
Under our Fourth Amendment jurisprudence, citizens can be subjected to a
*507
full custodial arrest only if the arresting officer has probable cause to detain them. “Probable cause to arrest exists when a reasonably cautious and prudent person would be justified in believing that the individual to be arrested had committed, was committing or was about to commit a crime.”
United States v. Tilmon,
In addition, precedent teaches that law enforcement officers may engage in brief investigative stops that need not be supported by probable cause, but instead by reasonable suspicion that the target has committed, is committing, or is about to commit a crime.
See Terry,
The line between a lawful
Terry
stop and an unlawful arrest: is not bright,
United States v. Vega,
Based on the facts presented here, we find that the FBI executed a constitutional Terry stop — not an arrest— in the Homan Square Theater parking lot, even though the agents blockaded Askew’s car and approached with guns drawn. The agents’ show of force corresponded to their reasonable suspicion that one of the people in the silver Hyundai was Askew, who was preparing to commit a drug-related crime. As we explain below, the inherent danger in stopping those suspected of drug trafficking, for which guns are known tools of the trade, in a public place where civilian lives might be at risk, warranted the level of intrusion in this instance.
1. Reasonable suspicion
A finding of reasonable suspicion supporting a
Terry
stop must be based on the totality of the circumstances presented to the officer at the time of the detention.
Scheets,
Yet Agent Benvenuto, the FBI agent in charge of the stop, testified that he received information from Williams, a cooperating witness, that Askew was to arrive at the theater at 11:00 A.M. for the purpose of making a PCP buy. While waiting *508 for Askew to arrive, Agent Benvenuto was in contact with Williams’s case agents, who were updating him as to Askew’s whereabouts based on Williams’s contemporaneous phone conversations with Askew. From these communications, Agent Ben-venuto knew when Askew’s arrival was imminent and that he was in a car, although not the white Cadillac that Askew originally claimed he would be driving. Agent Benvenuto, who was assigned to investigate drug trafficking organizations, explained his decision to stop the Hyundai Accent: “It has been [my] experience that when you arrange a buy-bust for a certain location and then a car arrives at that location driving in what I would describe as a suspicious manner, clearly looking for someone in that parking lot, it’s been my experience that that is the individual.” (Tr. at 114.)
The totality of the circumstances here firmly establishes reasonable suspicion, if not probable cause, for the stop. Although circling a parking lot looking for someone is most certainly an innocent act, we have acknowledged that “a pattern of behavior interpreted by the untrained observer as innocent may justify a valid investigatory stop when viewed collectively by experienced drug enforcement agents like [Agent Benvenuto].”
United States v. Lechuga,
2. Degree of intrusion
Having decided that the initial stop was justified under
Terry,
we must examine whether the manner in which it was executed — car blocked, guns drawn — -was “reasonably related in scope to the circumstances which justified the interference in the first place.”
Vega,
Drug arrests can warrant intrusive tactics because of their inherent danger. “Guns are among the tools of the drug trade[,]”
United States v. Rhodes,
We find the Terry stop lawful based on the particular circumstances of this case and, therefore, the judge did not commit any error, plain or otherwise, in allowing evidence collected as a result of the stop to be presented to the jury.
E. Askew’s Sentence
One final matter we must address is the effect of the recent Court decision in
United States v. Booker,
— U.S. -,
Askew failed to raise in the district court an Apprendi-based objection to his sentence, but following argument, we granted Askew leave to file a supplemental brief raising such a challenge in light of
Blakely v. Washington,
— U.S. -,
The record discloses that Askew received a sentence mandated by the Guidelines and increased on the basis of facts found by the judge, not the jury — in other words, Askew’s sentence was imposed under a sentencing scheme that we now know is unconstitutional. Askew’s sentence, therefore, was imposed in error, and the error is plain.
See United States v. Paladino,
As we concluded in
Paladino,
the “only practical way ... to determine whether the kind of plain error argued in these cases has actually occurred is to ask the district judge.”
Paladino,
On the other hand, if the district court decides that a different sentence would have been appropriate pursuant to its exercise of greater discretion, “we will vacate the original sentence and remand for re-sentencing.”
Paladino,
III. Conclusion
Because we find no merit in any of the arguments Askew raises on appeal, his conviction is Apfiemed. As to Askew’s sentence, however, we order a limited remand of this case in accordance with the remedial procedure adopted by this circuit in Paladino. The district court is directed to return this case to us at the completion of its sentencing determination, pursuant to the procedure set forth in Paladino.
Notes
. Askew testified that he declared bankruptcy in 1999 following release from prison for a non-drug-related felony.
. Although a conspiracy terminates when one member agrees to cooperate with the government,
Thomas,
. We also note that at no time did Askew make the argument he makes here, that the conspiracy instruction as originally given by the court was inadequate, lacking clarification as to Williams’s status as a government informant after her arrest and to its significance in terms of the conspiracy charge. By taking the position, in response to the jury’s questions, that the judge should direct the jury to the conspiracy instruction already provided and by requesting no clarifying language, Askew implicitly accepted the conspiracy instruction as a complete and accurate statement of the law. Thus, not only has he waived the argument that the district judge failed to provide appropriate supplemental instruction to the jury, he has effectively waived the related argument that the conspiracy instruction with which the jury was initially charged was flawed in such a way as to warrant a new trial.
