This is a consolidated direct appeal by six defendants convicted of various offenses stemming from a crack cocaine conspiracy. The defendants raise numerous issues on appeal. For the reasons stated below, we affirm in part and reverse in part.
I. Background
From the middle of 1995 until August 1, 1997, Christopher Bell (“Bell”) led a conspiracy to distribute crack cocaine in Southern Wisconsin. On August 7, 1997, a federal grand jury sitting in the Western District of Wisconsin returned a fourteen-count indictment against eleven individuals, including Kenyatta Brack (“Brack”), Patrick Henderson (“Henderson”), Willie Tyler (“Tyler”), Nicholas Martinez (“Martinez”), Maurita Stovall (“Stovall”), and Dana Richardson (“Richardson”). Count 1 of the indictment charged all the defendants with conspiracy to distribute cocaine base and to possess cocaine base with intent to distribute, in violation of 21 U.S.C. § 846. Count 2 charged Brack with possession of cocaine base with intent to distribute, in violation of 21 U.S.C. § 841(a)(1). Finally, counts 3, 4, 5, 7, 8, and 10 charged Richardson with possession of cocaine base with intent to distribute, and distribution of cocaine base, both in violation of 21 U.S.C. § 841(a)(1).
On January 30, 1998, Brack pled guilty to the conspiracy charge. However, he reserved the right to appeal the district court’s denial of his motions to suppress evidence found when the police strip searched him, and when they searched Room 109 of the Econolodge in Beloit, Wisconsin. Also on January 30, 1998, after fifing numerous pretrial motions, proposed voir dire questions, and proposed jury instructions, as well as participating in a final pretrial conference, Martinez entered a conditional plea of guilty to the conspiracy charge. Martinez’s trial was scheduled to begin three days later. Finally, on March 6, 1998, Richardson pled guilty to possession of cocaine base with intent to distribute. The remaining three appellants proceeded to trial before a jury.
At trial, both Bell and Martinez testified that Tyler was a distributor for the conspiracy. Bell further testified that his relationship with Tyler began in September 1996 and continued until August 1997. However, there is some confusion about whether Tyler distributed drugs for Bell during the entire year or for only eight months. In any case, the conspiracy delivered half an ounce to an ounce of crack to Tyler each week. Bell testified that much of the crack was given to Tyler on credit, although Martinez testified that he was under the impression that Tyler usually paid Bell in advance. Finally, Bell testified that he wanted Tyler to sell drugs for him because Tyler was able to sell to people with whom Bell didn’t otherwise do business.
On February 6, 1998, the jury found Henderson, Tyler, and Stovall guilty of the conspiracy charge. On March 20, 1998, Tyler submitted a six-page, single-spaced, handwritten account of his offense and contended that he qualified for sentencing under the safety valve provisions. 18 *754 U.S.C. § 3553(f); U.S.S.G. § 5C1.2. Tyler’s attorney also wrote to the government to confirm Tyler’s willingness to submit to a safety valve interview. However, the government took the position that Tyler had not provided truthful information. It pointed to inconsistencies between Tyler’s safety valve statement and the sworn testimony of Bell and Martinez. No interview was conducted because of the government’s lack of faith in the veracity of Tyler’s statement. The district court held that Tyler had not met the safety valve requirements.
Richardson’s truthfulness was also called into question at sentencing. At issue was a typed statement by Richardson in which he denied that he was a member of the conspiracy, and claimed that he was merely an independent dealer who was supplied by Bell. In addition, Richardson estimated that he sold between one and one and a half ounces of cocaine a month. These assertions conflicted with statements made by Bell and Martinez to police shortly after they were arrested. Both Bell and Martinez told police that Richardson was a member of the conspiracy and that he sold between one and four ounces of cocaine a week. The district court found that Richardson was a member of the conspiracy, that his relevant conduct involved more than 1.5 kilograms of cocaine base, and that he had falsely denied relevant conduct. Accordingly, the lower court refused to reduce Richardson’s offense level for acceptance of responsibility.
Martinez also experienced some difficulty at sentencing. The district court granted him a two-level sentence reduction for acceptance of responsibility, but it denied him an additional one-level reduction because he pled guilty only three days before trial. Furthermore, the court gave him a two-level sentence enhancement for possession of a dangerous weapon.
As for Stovall, her sentence was enhanced by two levels for using a minor to commit a crime. In applying the enhancement, the district court relied on recordings of two telephone conversations that took place on July 12 and July 23, 1997. During both phone calls, Stovall asked Maurice Tucker ( “Tuck”), a fourteen year old who worked for Bell’s organization, to bring her some crack. The court found that these conversations showed that Sto-vall asked Tuck “to do work for her that involved the distribution of drugs.” (Tr. vol. 3 at 28.)
The following table summarizes the offenses of conviction and sentences of the appellants.
Appellant Offense of Conviction Sentence
Brack conspiracy to distribute & to possess with intent to distribute 188 mo.
Henderson conspiracy to distribute & to possess with intent to distribute 360 mo.
Tyler conspiracy to distribute & to possess with intent to distribute 188 mo.
Martinez conspiracy to distribute & to possess with intent to distribute 250 mo.
Stovall conspiracy to distribute & to possess with intent to distribute 235 mo.
Richardson possession with intent to distribute 324 mo.
II. Discussion
A. Brack
1. Suppression of Evidence Found in Room 109 of the Econolodge
Brack’s first argument on appeal is that there was no probable cause to support the search warrant for Room 109 of the Econolodge and that, consequently, the district court should have suppressed any evidence found when the room was searched. Before we discuss probable cause, however, we must address the government’s contention that Brack is not entitled to challenge the existence of probable cause because he has not shown that “he personally ha[d] an expectation of privacy in the place searched, and that his expectation [wa]s reasonable.”
Minnesota v. Carter,
Probable cause exists when “the known facts and circumstances are sufficient to warrant a man of reasonable prudence in the belief that contraband or evidence of a crime will be found.”
Ornelas v. United States,
Brack’s argument is essentially that the Rock County Court Commissioner was presented with insufficient reliable evidence to support a finding of probable cause. He notes that an official cannot merely ratify “the bare conclusions of others,”
Gates,
Thus modified, the affidavit reveals that on September 20, 1996, an informant told police that drugs were being sold from Room 109 of the Econolodge. The informant also told police that Room 109 was occupied by a black man who was bald, six feet tall, and weighed 160 pounds. The police believed that the man’s name was Kenyatta. Independent investigation showed that Room 109 had been rented by Selean Turner (“Turner”) on September 20, 1996, and that she had reserved the room through October 13, 1996. Police observed a car registered to Turner parked nearby. On September 23, 1996, an informant made a controlled purchase of cocaine in Room 109. The man who sold the cocaine to the informant matched the description provided by the first (or same) informant. Police observed that Turner’s car was parked near the room during the controlled purchase. Finally, an informant of unknown reliability told *756 police that Anthony Smith (“Smith”) (a notorious drug dealer) and “Kenyatta” would be going to Chicago to buy cocaine on September 26, 1996 and would be returning in the evening on September 27 or 28. The informant further specified that Smith and “Kenyatta” would be driving Turner’s car. Based on this information, the police sought and obtained a search warrant contingent on the return of Smith and/or a black male meeting the description of “Kenyatta” to Room 109 in the evening on September 27 or 28, 1996.
In the early evening on September 27, 1996, the police observed Turner driving her own car near the hotel. They pulled her over and took her into custody for questioning. Later that evening, a man who matched the description of “Kenyatta” (and who turned out to be Kenyatta Brack) returned to Room 109. When he left the hotel in a car, the police pulled him over and took him into custody pursuant to an outstanding traffic arrest warrant. The police then executed the search warrant for Room 109, seizing drugs, a scale, a pager, and some clothes.
Brack contends that the information provided by the confidential informants) was unreliable and that, therefore, it did not provide a sufficient basis for the Court Commissioner to conclude that probable cause existed. According to the case law of this Circuit, the factors that suggest that a confidential source’s information is reliable include: “(1) firsthand observation by the informant; (2) degree of detail provided; (3) corroboration of the informant’s information by an officer’s independent investigation and (4) the fact that the informant testified at the probable cause hearing.”
Reddrick,
In this ease, the controlled purchase on September 23, 1996 confirmed that “Kenyatta” was selling drugs out of Room 109.
See Reddrick,
The reliability of the tip was further bolstered by the nature of the details provided. Although the details were relatively few, they related to future actions of third parties, which are “ordinarily not easily predicted.”
Id.
at 245,
We are not persuaded to the contrary by the fact that Brack did not return in Turner’s car as the informant predicted. In
Gates,
the informant incorrectly predicted that Mrs. Gates would return from Florida by plane after dropping off her car to be loaded with drugs. Instead, she remained with the car and drove back to Illinois
*757
accompanied by her husband. The Supreme Court explained that informants need not be infallible, and found that the single inaccuracy was not enough to undermine the informant’s credibility.
Gates,
Brack next contends that the search warrant was invalid because it did not satisfy the three additional requirements for anticipatory search warrants. These requirements are: (1) that the affidavit present independent evidence that gives rise to probable cause to believe that the contraband will be located at the premises at the time of the search; (2) that the contraband be on a “sure course” to the location to be searched; and (3) that the conditions governing the execution of the warrant be explicit, clear, and narrowly drawn.
Dennis,
We have already addressed the requirement that an affidavit in support of an anticipatory warrant show probable cause to believe that contraband will be located at the premises at the time of the search. Therefore, we proceed directly to Brack’s contention that the affidavit did not establish that the drugs were on a “sure course” to Room 109 of the Econolodge. The purpose of the sure course requirement is to prevent law enforcement authorities or third parties from mailing or otherwise sending a controlled substance to a residence to “create probable cause to search the premises where it otherwise would not exist.” Id. at 529. The requirement ensures that a sufficient nexus between the parcel and the place to be searched exists. Id.
When contraband is delivered to the location to be searched by controlled delivery, there is always a danger that the government’s involvement will result in drugs being sent to a location that they otherwise would not have been sent to. For example, a courier intercepted while carrying drugs might implicate someone else in order to win himself a lighter punishment. In Brack’s case, however, neither the government nor a third party was involved in delivering the contraband to Room 109. The drugs were delivered by Brack himself. For this reason, we doubt that the “sure course” requirement is applicable.
See United States v. Rowland,
In Brack’s final attack on the search warrant, he asserts that the triggering condition for executing the warrant was too broad. In particular, he argues that the time frame specified in the affidavit was too long. The purpose of the requirement that warrants conditioned on future events be narrowly drawn is to avoid premature execution as a result of manipulation or misunderstanding by the police.
United States v. Garcia,
Brack’s reliance on the First Circuit’s decision in
United States v. Ricciardelli,
Even if the warrant was deficient in one of the ways claimed by Brack, the evidence seized during the execution of the warrant was admissible under the good faith exception to the exclusionary rule. According to the rule announced in
United States v. Leon,
“[i]n the absence of an allegation that the magistrate abandoned his detached and neutral role, suppression is appropriate only if the officers were dishonest or reckless in preparing their affidavit or could not have harbored an objectively reasonable belief in the existence of probable cause.”
2. Suppression of Evidence Seized During Strip Search
Brack next challenges the denial of his motion to suppress evidence seized when he was strip searched on September 27, 1996. He argues that the strip search violated his Fourth Amendment right to be free from unreasonable searches. To determine whether the search was reasonable, we balance the government’s need to conduct the search against the invasion of Brack’s personal interests.
See Kraushaar v. Flanigan,
As we noted above, Brack was taken into custody pursuant to an outstanding traffic arrest warrant when he left Room 109 of the Econolodge on the evening of September 27, 1996. He was then taken to the Beloit Police Station while police searched his room. When he arrived at the station, he immediately asked for toilet paper so that he could relieve himself. Given that Brack was a suspect in a drug investigation, his request was met with suspicion. Officer McMahon instructed Brack to undress and turn around. When he did so, McMahon observed a piece of tissue in the crease of Brack’s buttocks. At McMahon’s instruction, Brack removed the tissue and two plastic bags. One bag contained cocaine and the other contained marijuana.
It is well established that “officials have a legitimate and substantial need to prevent arrestees from bringing weapons or contraband into ... a [detention] facility.”
Kraushaar,
Brack’s only argument to the contrary is that the search violated Wisconsin law, which requires that no strip search be conducted without written authorization from the top official of the police department. As we explained in
Burnham,
however, “a state may provide greater protections under its laws than the Constitution requires.”
B. Henderson
1. Suppression of Wiretap Evidence
Henderson’s brief incorporates by reference his arguments “outlined in extensive briefs filed in the trial court” that: (1) there was no need for a wiretap of the telephone at Vision Plus (a front business for Bell’s organization); and (2) the wiretap failed to minimize interception of non-relevant communication. We decline to address these issues and by way of explanation incorporate by reference our explanation in
DeSilva v. DiLeonardi,
2. Mistrial
Henderson’s second argument on appeal is that the district court should have granted him a mistrial because Tyler’s attorney implied that Henderson was a gang member during her cross-examination of Bell. The district judge is in the best position “to weigh the imponderables involved in a judgment of prejudice.”
United States v. Brisk,
The following exchange took place between Tyler’s attorney and Bell:
Q: You testified quite awhile ago on direct examination with Mr. Vaudreuil that you wanted to sell to Mr. Tyler because he could sell to folks that you couldn’t; is that correct?
A: That I didn’t trust, yes.
Q: And by “folks” you meant the gang folks; right?
A: Yes.
Q: But in fact you had a whole lot of people who were -members of that same organization already working for you; did you not?
A: No I did not.
Q: Well, Pat G. was.
(Tr. vol. 2 at 99.) Because Pat G. is Henderson’s nickname, Henderson’s attorney objected. The court denied Henderson’s request for a mistrial but offered to give a corrective instruction. Henderson’s attorney declined because he did not want to draw additional attention to the matter. No further mention was made of Henderson’s gang affiliation. Under these circumstances, and given the substantial evidence against Henderson, Bell’s comments were not so prejudicial that they deprived Henderson of a fair trial. Therefore, the district court did not abuse its discretion when it denied Henderson’s request for a mistrial.
*760 C. Tyler
1. Sufficiency of the Evidence
Tyler’s first argument on appeal is that the government proved only that he had a buyer-seller relationship with Bell, not.that he was a member of the Bell conspiracy. In making this sufficiency challenge, Tyler “faces a nearly insurmountable hurdle ... [in that] we consider the evidence in the light most favorable to the Government, defer to the credibility determination of the jury, and overturn a verdict only when the record contains no evidence, regardless of how it is weighed, from which the jury could find guilt beyond a reasonable doubt.”
United States v. Szanuark,
In
United States v. Lechuga,
we held that in order to prove conspiracy to distribute a controlled substance, the government must show the existence of “an agreement to commit a crime other than the crime that consists of the sale itself.”
Viewed in the light most favorable to the government, the evidence in this case showed that Bell fronted between half an ounce and one ounce of crack per week to Tyler for at least eight months. (Tr. vol. 5 at 31-34). Furthermore, Bell testified that he agreed to sell to Tyler in order to expand the conspiracy’s market, (Tr. vol. 5 at 33), suggesting a long-term arrangement.
See Lechuga,
2. Buyer-Seller Instruction
In a related argument, Tyler challenges the district court’s choice of buyer-seller jury instruction. Tyler’s proposed instruction stated:
The mere fact that a defendant may have bought or sold cocaine [from or to] another defendant is not sufficient, without more, to establish that either defendant was a member of the conspiracy. This is true even if the defendant bought the cocaine repeatedly and resold it.
The judge gave the following instruction instead:
The existence of a mere buyer-seller relationship between a defendant and another person, without more, is not sufficient to establish a conspiracy. The fact that a defendant may have bought cocaine from another person and sold *761 cocaine to another person is not sufficient, without more, to establish that the defendant was a member of the charged conspiracy.
(Tr. vol. 1 at 108-9.) Thus, the controversy centers on the admonishment in the last sentence of Tyler’s proposed instruction that evidence of repeated purchases of drugs for resale does not establish participation in a conspiracy.
At the outset, we note that Tyler’s situation is distinguishable from that of a defendant who is not given a buyer-seller instruction at all.
See United States v. Menting,
In this case, the instruction given by the district court was a true statement of the law.
See, e.g., Meyer,
3. Eligibility for Safety Valve Sentencing
Tyler next argues that he was entitled to be sentenced under the safety valve provisions set forth at 18 U.S.C. § 3553(f), and U.S.S.G. § 5C1.2. A defendant who meets the requirements of these provisions must be sentenced in accordance with the Sentencing Guidelines, and is exempt from any otherwise applicable statutory minimum sentence. In addition, if the defendant’s offense level is 26 or higher, the court will reduce the level by two pursuant to U.S.S.G. § 2Dl.l(b)(6). To be eligible for these benefits, a defendant must prove by a preponderance of the evidence,
United States v. Ramirez,
(1) the defendant does not have more than 1 criminal history point, as determined under the sentencing guidelines;
(2) the defendant did not use violence or credible threats of violence or possess a firearm or other dangerous weapon (or induce another participant to do so) in connection with the offense;
(3) the offense did not result in death or serious bodily injury to any person;
(4) the defendant was not an organizer, leader, manager, or supervisor of others in the offense, as determined under the sentencing guidelines and was not engaged in a continuing criminal enterprise, as defined in section 408 of the Controlled Substances Act; and
(5) not later than the time of the sentencing hearing, the defendant has truthfully provided to the Government all information and evidence the defendant has concerning the offense or offenses that were part of the same course of conduct or of a common scheme or plan, but the fact that the defendant has no relevant or useful other information to provide or that the Government is already aware of the information shall not preclude a determination by the court that the defendant has complied with this requirement.
18 U.S.C. § 3553(f).
See also
U.S.S.G. § 5C1.2. The district court held that Tyler had not met the fifth criterion because he had not truthfully provided the government with all the information and evidence he possessed. We review the district court’s factual findings for clear error and its interpretation of the safety valve provisions
de novo. See Ramirez,
The transcript of Tyler’s sentencing hearing reveals that the district judge was uncertain about whether Tyler had a motivation to lie in his safety valve statement. The judge stated that “it just [didn’t] make sense to [him] that Mr. Tyler was being untruthful” because the alleged lies “didn’t affect the calculation of relevant conduct.” (Tr. vol. 4 at 35.) The judge did speculate briefly that Tyler might have been motivated to lie in order to maximize his chances on appeal. (Tr. vol. 4 at 36). However, the judge did not decide whether Tyler had been truthful, explaining that he was “a little more troubled about the fact that Mr. Tyler confined his statement to just what was known at trial.” (Tr. vol.4 at 36.) Ultimately, the court found that Tyler’s statement was not “the outpouring of information and evidence that ... is required under the safety valve,” and that “[t]he import and the intent of [Tyler’s] statement seem[ed] to be to explain what [Tyler] did or didn’t do and to somehow to some extent minimize his involvement in th[e] conspiracy.” (Tr. vol. 4 at 37-38.) The judge concluded: “I’m just not persuaded that the defendant has made the showing that I believe is his burden to *763 make to show that he’s entitled to the safety valve.” (Tr. vol. 4 at 38.)
Because the district court based its decision on the incompleteness of Tyler’s statement rather than on its untruthfulness, the issue before us is whether, assuming that Tyler’s written statement was truthful, the statement combined with Tyler’s offer to submit to a safety valve interview satisfied the safety valve disclosure requirement. Tyler, of course, argues that he should not be penalized for the government’s unwillingness to meet with him. The government, for its part, contends that because it believed that Tyler’s statement was not truthful, it was under no obligation to follow up with an interview. This argument confuses the issues. Although the government was not required to give Tyler a second chance to tell the truth, it could not complain of incompleteness when it refused to allow him to finish telling his story. As the Fourth Circuit noted in
United States v. Beltran-Ortiz,
“[djebrief-ing by the Government plays an important role in permitting a defendant to comply with the disclosure requirement of the safety valve provision
and in convincing the Government [and court] of the fullness and completeness of a defendant’s disclosure.”
Nonetheless, a defendant cannot satisfy the disclosure requirement simply by notifying the court of his willingness to submit to a safety valve interview.
See United States v. Ortiz,
D. Martinez
1. Weapons Enhancement
During the execution of a search warrant at Martinez’s home, police found an unloaded handgun and two unloaded rifles. In addition, it is undisputed that guns were stored at a stash house to which Martinez had access. Based on these facts, the district court enhanced Martinez’s sentence by two levels for possession of a dangerous weapon. See U.S.S.G. § 2Dl.l(b)(l). Martinez challenges the enhancement on the grounds that he did not possess the weapons found at his home, either actually or constructively, but was merely storing them at Bell’s request. We review the district court’s application of the weapons enhancement for clear error.
A weapons enhancement pursuant to U.S.S.G. § 2Dl.l(b)(l) is applica
*764
ble when: “ (1) the defendant possessed a weapon, either actually or constructively,
United States v. Adams,
At sentencing, the district court held that “it d[id]n’t really matter whether Mr. Martinez had personal control over the guns [because] [i]t was reasonably foreseeable to him that Mr. Bell kept firearms in connection with the conspiracy.” (Tr. vol. 2 at 11.) This holding was not clearly erroneous. It is undisputed that Bell owned the weapons kept at the stash house; and “guns found in close proximity to illegal drugs are presumptively considered to have been used in connection with the drug trafficking enterprise.”
Adams,
2. Acceptance of Responsibility
Martinez next challenges the district court’s refusal to grant him an additional one-level reduction for timely acceptance of responsibility. Under the Sentencing Guidelines, a defendant who “clearly demonstrates acceptance of responsibility for his offense,” is entitled to a two-level sentence reduction. U.S.S.G. § 3El.l(a). A defendant who qualifies for this two-level decrease and whose offense level was greater than 16 prior to the decrease, is eligible for an additional one-level decrease if the defendant has “assisted authorities in the investigation or prosecution of his own misconduct” by either:
(1) timely providing complete information to the government concerning his own involvement in the offense; or
(2) timely notifying authorities of his intention to enter a plea of guilty, thereby permitting the government to avoid preparing for trial and permitting the court to allocate its resources efficiently.
U.S.S.G. § 3El.l(b). It is the defendant’s burden to establish by a preponderance of the evidence that he is entitled to the additional reduction.
United States v. Wetwattana,
It is undisputed that Martinez fully cooperated with the government after his guilty plea. Therefore, the only issue for our consideration is the timeliness of Martinez’s cooperation and plea. As a rule, “conduct qualifying for a decrease in offense level under subsection (b)(1) or (2) will occur particularly early in the case.” U.S.S.G. § 3El.l(b), Application Note 6. However, the timeliness requirement for an additional acceptance of responsibility reduction is defined in functional rather than in temporal terms.
Wetwattana,
Most of the parties’ arguments have focused on the timeliness of Martinez’s guilty plea under § 3El.l(b)(2). The government points out that because Martinez pled guilty three days before trial, it was forced to prepare a case against him, and then had to revamp its trial strategy as to the remaining defendants on extremely short notice. Furthermore, the timing of the plea made it necessary for the government to respond to Martinez’s numerous
*765
pretrial motions. Mai'tinez argues that the government had to prepare for trial anyway because four of his co-defendants proceeded to trial. As we explained in
United States v. Francis,
this argument is unavailing. “Even though a trial was to be held anyway for the other ... defendants, the government was obviously forced to specifically prepare for each and every defendant.”
United States v. Francis,
Martinez’s cooperation with the government also came too late to qualify him for an additional acceptance of responsibility reduction. Section 3El.l(b)(l)’s requirement that a defendant timely provide the government with complete information concerning his own involvement in the offense must be viewed in light of the broader requirement that the defendant assist authorities in the investigation or prosecution of his own misconduct.
See United States v. Lancaster,
E. Stovall
Enhancement for Use of a Minor
Stovall’s sole argument on appeal is that her sentence should not have been enhanced, pursuant to U.S.S.G. § 3B1.4, for using a minor to commit a crime. We review the district court’s interpretation of U.S.S.G. § 3B1.4 de novo.
U.S.S.G. § 3B1.4 provides for a two-level sentence enhancement “[i]f the defendant used or attempted to use a person less than eighteen years of age to commit the offense.” The phrase “ ‘[u]sed or attempted to use’ includes directing, commanding, encouraging, intimidating, counseling, training,' procuring, recruiting, or soliciting.” U.S.S.G. § 3B1.4, Application Note 1. Stovall argues that under our decision in
United States v. Porter,
In this case, a wiretap twice intercepted phone calls by Stovall to Tuck, who was fourteen years old. During each call, Sto-vall placed an order for crack cocaine with Tuck, and requested that he deliver the drugs to her home. Based on this evidence, the district court found that Stovall had asked Tuck “to do work for her that involved the distribution of drugs.” (Tr. vol. 3 at 28.) The fact that Tuck was a high-ranking, salaried member of Bell’s organization is irrelevant. The district court did not err in concluding that Stovall used Tuck in the commission of a crime.
F. Richardson
1. Relevant Conduct
The Sentencing Guidelines provide that, “in the case of a jointly under *766 taken criminal activity (a criminal plan, scheme, endeavor, or enterprise undertaken by the defendant in concert with others, whether or not charged as a conspiracy),” relevant conduct includes “all reasonably foreseeable acts and omissions of others in furtherance of the jointly undertaken criminal activity.” U.S.S.G. § lB1.3(a)(l)(B). Thus, in a conspiracy situation, a defendant is accountable for the conduct of others if the conduct was “(i) in furtherance of the jointly undertaken criminal activity; and (ii) reasonably foreseeable in connection with that criminal activity.” U.S.S.G. § lB1.3(a)(l), Application Note 2. In the case of a jointly undertaken offense involving controlled substances, “the defendant is accountable for all quantities of contraband with which he was directly involved and ... all reasonably foreseeable quantities of contraband that were within the scope of the criminal activity that he jointly undertook.” U.S.S.G. § lB1.3(a)(l), Application Note 2. The district court found that Richardson was a member of the Bell conspiracy, and consequently that his relevant conduct involved more than 1.5 kilograms of cocaine base. Richardson attacks this relevant conduct calculation by insisting that he was an independent dealer, not a member of the Bell conspiracy. We review for clear error.
Shortly after they were arrested, Bell and Martinez told police that: Richardson was a salaried member of the conspiracy who -made $300-$500 a week; the conspiracy provided Richardson with an apartment and a vehicle; Bell paid Richardson’s bail when Richardson was arrested for selling crack in January of 1997; and Richardson sold between one and four ounces of crack a week for the conspiracy. In a four-page written statement, Richardson denied these assertions and claimed that he was merely an independent dealer whose drugs were supplied by Bell. Furthermore, he estimated that he sold one to one and a half ounces of cocaine a month.
At his sentencing hearing, Richardson argued that Bell’s and Martinez’s unsworn statements were inconsistent with their sworn testimony at trial. More specifically, Richardson pointed out that neither Bell nor Martinez mentioned him when they were asked to list the salaried members of the conspiracy under oath. The district court was unimpressed by this omission, however, reasoning that “because Mr. Richardson was not one of the defendants that was standing trial at the time ... [tjhere was no reason for Mr. Bell or Mr. Martinez to talk about Mr. Richardson]” (Tr. vol. 1 at 23.) Consistent with this interpretation, the record shows that when Bell was specifically asked about Richardson during cross-examination by Tyler’s counsel, Bell stated that he paid Richardson a salary during the time that Richardson was a part of the organization. (Tr. vol. 2 at 92-93.) Richardson’s attempt to bolster the credibility of his own story by offering his landlord’s affidavit to show that he had been paying his own rent also fell flat. The district court found that the affidavit showed only that Bell did not pay Richardson’s rent directly, but did not preclude the possibility that Bell gave Richardson money to pay his rent.
Given these conflicting accounts of Richardson’s involvement in the conspiracy, the district court was called upon to make a credibility determination — the type of determination to which we give the utmost deference.
See Brisk,
*767 2. Acceptance of Responsibility
Unlike Martinez, Richardson did not even receive the two-level sentence reduction for acceptance of responsibility, let alone the additional one-level reduction for timely pleading guilty or providing complete information to the government. U.S.S.G. § 3E1.1. The district court declined to reduce Richardson’s sentence on the grounds that Richardson had falsely denied relevant conduct. See U.S.S.G. § 3El.l(a), Application Note 1(a) (“A defendant who falsely denies ... relevant conduct that the court determines to be true has acted in a manner inconsistent with acceptance of responsibility.”). Again the standard of review is clear error. Therefore, our conclusion, in the previous section, that the district court did not clearly err in calculating Richardson’s relevant conduct, notwithstanding Richardson’s denial of such conduct, is dispositive.
Conclusion
The district court’s judgment is Affirmed in all respects except that Tyler’s sentence is Vaoated and his case is Remanded for re-sentencing consistent with the views expressed in this opinion.
Notes
. The government purports to challenge Brack’s standing. However, "in determining whether a defendant is able to show the violation of his (and not someone else's) Fourth Amendment rights, the definition of those rights is more properly placed within the purview of substantive Fourth Amendment law than within that of standing.”
Carter,
. Although Henderson’s brief does not exceed this Circuit's page limit (the brief is ten pages long and contains only two pages of argument), we recently explained that "[e]ven when a litigant has unused space ... incorporation [by reference] is a pointless imposition on the court’s time.”
DeSilva,
. Given this holding, we need not address Tyler's related claim of ineffective assistance of counsel.
