The defendants in this action were convicted of conspiracy to possess and distribute cocaine in violation of 21 U.S.C. §§ 841(a)(1) and 846. They raise multiple issues in their appeals, including challenges to the jury selection process, to evidence admitted at trial, and to their sentences. For the reasons set forth below, we AFFIRM the convictions and sentences of all of the defendants except Allie Richard Buchanan, IV. As to Buchanan, we AFFIRM his conviction, but VACATE his sentence and REMAND the same for reconsideration in light of the district court’s erroneous belief that it did not have discretion to depart from the applicable sentencing guideline. I. BACKGROUND A. Factual background This case involves a large-scale drug organization involving numerous individuals, including Rodney D. Atkinson, Buchanan, Albert Derring, Derrick C. Flowers, Darryl Ford, Eurtis Jones, George Kellum, Otis Murray, III, Troy Swindle, and Charles Washpun, all of whom are African-American. The organization, which began operating in and around Kalamazoo, Michigan in 1990, was formed by Keylen Tremell Blackmon, Buchanan, and Scott Hughes. In broad outline, Blackmon, Buchanan, and Hughes obtained large quantities of cocaine, primarily from sources in Chicago, and would then distribute the drugs—in some instances after converting it into cocaine base (“crack”)—to 4 United States v. Nos. 98-1353/1391/1533/1534/ Nos. 98-1353/1391/1533/1534/ United States v. 25 Buchanan, et al. 1535/1537/1538/1590/1594/1780 1535/1537/1538/1590/1594/1780 Buchanan, et al. various individuals in and around Kalamazoo. Atkinson, photographs had an impact on the outcome of this trial. Their Derring, Flowers, Ford, Jones, Kellum, Murray, Swindle, and introduction was thus harmless error. Washpun were all purchasers and/or sellers of the drugs obtained by Blackmon, Buchanan, and Hughes. The details of the charged conspiracy will, to the extent necessary, be discussed in connection with the defendants’ specific assignments of error. B. Procedural background On June 5, 1997, a grand jury indicted twenty-four individuals—including Buchanan, Derring, Ford, Jones, Kellum, Murray, Swindle, and Washpun—with conspiracy to possess and distribute cocaine and cocaine base in violation of 21 U.S.C. §§ 841(a)(1) and 846. Four of the individuals were also charged with specific instances of possessing or distributing the illegal drugs. A superseding indictment was filed on July 10, 1997, in which another individual not involved in these appeals was added to the conspiracy charge. The superseding indictment also contained money laundering charges and forfeiture allegations against some of the defendants. On October 1, 1997, Buchanan pled guilty to the conspiracy charge. A second and final superseding indictment was issued on October 7, 1997. The new conspiracy charge omitted those defendants who were originally indicted but who had since pled guilty, such as Buchanan, and added four new individuals, including Atkinson and Flowers. In addition to those modifications, the alleged ending date of the conspiracy was changed from July of 1996 to June of 1997. Derring pled guilty on October 29, 1997. By the beginning of 1998, all but fifteen of those indicted in the case had entered guilty pleas. Due to the relatively large number of remaining defendants, the district court assigned each individual to one of two trials. Atkinson, Flowers, Ford, Jones, Kellum, Murray, Swindle, and Washpun constituted the second group. On January 27, 1998, 24 United States v. Nos. 98-1353/1391/1533/1534/ Nos. 98-1353/1391/1533/1534/ United States v. 5 Buchanan, et al. 1535/1537/1538/1590/1594/1780 1535/1537/1538/1590/1594/1780 Buchanan, et al. to create the inference that these individuals were engaged in one day after their trial began, Swindle moved for a mistrial illegal narcotics activity at those times. Nor are we on the basis that Blackmon, without warning, revealed to the comforted, as the district court is, by the fact that the jurors jury that Swindle had made a proffer to the government that were aware of and could “discount” the possible problems he was, in fact, guilty of the offenses alleged in the with dog-sniff evidence.

In the context of this case, with The defendants then appealed, setting forth a variety of the racial implications resulting from an all-white jury and an arguments relating to the jury selection process, the all-black set of defendants, I worry that the photographs, government’s arrangements with certain witnesses, evidence introduced as early in the trial as they were, likely had an admitted at trial, and their sentences.

Kentucky, 476 U.S. 79 in part) (footnotes omitted) (emphasis supplied in original). (1986), is entitled to great deference, and this court will not disturb that ruling unless it is clearly erroneous. See Given the unrebutted statistical studies in this and other Hernandez v. New York, 500 U.S. 352, 364-65 (1991). cases, we find Judge Becker’s view compelling. We believe “Whether a defendant has been denied his right to a jury that courts should generally presume against the admissibility selected from a fair cross-section of the community is a mixed of dog-sniff evidence unless the government offers other question of law and fact, which we review de novo.” United evidence showing a direct nexus between illegal narcotics, the States v.

The defendants’ Batson objection evidence in question. First, as in Carr, the government did not attempt to rebut the contamination studies. Indeed, one During jury selection, the government used a peremptory officer testified that she was aware of studies showing that as challenge to strike the only African-American person selected much as seventy to ninety percent of currency is contaminated for the jury. Citing Batson, the defendants argued that with some amount of controlled substances, J.A. at 1034-35, because all of the defendants were African-American, the and none of the witnesses who testified as to the dogs’ challenge was racially motivated. In response, the training countered those findings. Further, in neither case was government asserted that it excused the juror because of an there a nexus between the currency found and illegal answer she provided in response to a written question asked narcotics. The dog sniff in Murray’s case followed a traffic of all potential jurors. The question was as follows: “What stop, and although Murray was found with a large amount of newspapers, magazines and kinds of books do you read?” cash, he possessed no narcotics. Similarly, the dog sniff in The juror at issue answered: “Grand Rapids press . . . , I read Washpun’s case came after a routine traffic stop of a car in mysteries, romances and my Bible.

The prosecutor must convey a reason that is has circulated in a major metropolitan center (at which “clear and reasonably specific.” the studies are directed) is meaningless and likely quite unfairly prejudicial, see Fed.

It is thus my considered opinion that the fact that numerous studies by Here, the government offered its reason for striking the governmental and private agencies, studies which stand juror in question before the district court could evaluate unrefuted, strongly suggest that a trained canine will alert whether the defendants had set forth a prima facie case.

In recent years, this court and others have expressed method and manner of the jury selection skepticism regarding the probative value of dog-sniff process For the first time on appeal, the defendants take issue with the method and manner of the jury selection process.

Issue regarding leniency offered certain government sentencing guideline. witnesses The defendants contend that, by offering leniency to several witnesses who testified at trial, the government violated 18 U.S.C. § 201. That section provides, in pertinent part, as follows: Whoever . . . directly or indirectly, gives, offers or promises anything of value to any person, for or because of the testimony under oath or affirmation given or to be given by such person as a witness upon a trial, hearing, or other proceeding, before any court . . . shall be fined under this title or imprisoned for not more than two years, or both. Id. § 201(c)(2). The defendants’ challenge essentially invokes the now well-known Tenth Circuit decision of United States v. Singleton, 144 F.3d 1343 (10th Cir. 1998), which has since been vacated and rejected en banc, 165 F.3d 1297 (10th Cir. 1999). Moreover, this court has previously ruled that such prosecutorial conduct does not implicate § 201(c)(2). See United States v. Ware, 161 F.3d 414, 418-24 (6th Cir. 1998) (holding that § 201(c)(2) does not preclude the government from offering leniency to a defendant’s accomplice in exchange for truthful testimony against the defendant). Accordingly, we find no merit in this argument. C. Issues regarding evidence admitted during the trial 1.
