United States v. Emmanuel John, 27 F.4th 644

Background

ATF used a paid informant, Yien Chiek, who arranged and participated in controlled purchases of firearms from members of a South Sudanese community in Omaha; ATF provided surveillance, an audio/video-equipped vehicle, and controlled funds.
On July 19 and July 31, 2018, controlled buys occurred involving Kan Tap, Reuben Rowe, and Emmanuel John; recordings show John present on July 19 and involved in subsequent transactions.
Between August 15 and August 24, 2018, John sold or facilitated the sale of additional handguns to Chiek; over 36 days John was connected to eight firearms in six transactions.
John was prosecuted under 18 U.S.C. §§ 922(g)(1) and 924(a)(2), tried, and convicted on six counts after a second superseding indictment; he sought an entrapment instruction and a mistrial, and later argued sentencing manipulation and unreasonableness.
The district court denied the entrapment instruction and mistrial, found no sentencing manipulation, and sentenced John to 290 months’ imprisonment (well above the Guidelines range of 121–151 months).
The Eighth Circuit affirmed, rejecting John’s challenges to the denial of an entrapment instruction, denial of mistrial, sentencing-manipulation claim, and procedural and substantive reasonableness challenges to the 290‑month term.

Issues

Issue	Plaintiff's Argument (John)	Defendant's Argument (Government)	Held
Whether the district court erred by refusing an entrapment instruction	Chiek (via ATF) induced or implanted the criminal design; entrapment jury instruction required	No evidence of inducement; John was predisposed and initiated some contacts	Denial affirmed — no sufficient evidence of inducement to warrant instruction
Whether the court abused discretion in denying a mistrial after cross-examining a witness about gang/violence topics	Cross-examination breached stipulation and introduced prejudicial testimony linking John to violent/criminal activity	Any improper question was cured by striking the question and jury instruction; evidence of guilt was strong	Denial affirmed — no abuse of discretion; curative instruction sufficed
Whether government engaged in sentencing manipulation by continuing controlled buys to increase John’s exposure	Government continued the operation solely to raise number of guns and thereby inflate sentencing range	Investigation had legitimate law‑enforcement aims (identify other traffickers, remove guns, preserve informant utility)	Denial affirmed — no proof government acted solely to enhance sentence
Whether the 290‑month sentence was procedurally or substantively unreasonable	Sentence was procedurally flawed and substantively excessive (nearly double Guidelines)	Court considered §3553(a) factors, defendant’s record, number/stolen nature of guns, deterrence; afforded deference to district court	Affirmed — no procedural error and sentence not an abuse of discretion
