   U.S. District Court for the Northern District of Iowa - Waterloo   
   [PUBLISHED] [Shepherd, Author, with Loken and Erickson, Circuit Judges] 
   Criminal case - Criminal law and sentencing. The district court did not 
   err in denying defendant Williams's motion to suppress wiretap evidence as 
   the application for the wiretap established the wiretaps were necessary; 
   the district court did not abuse its discretion by limiting defendant 
   Williams's cross-examination of cooperating witnesses about their 
   potential sentences or rejecting his request to introduce their plea 
   agreements; the district court did not err in rejecting defendant 
   Williams's request for a multiple-conspiracies instruction as such an 
   instruction was not supported by the evidence at trial, which established 
   a single conspiracy; no error in applying enhancements to defendant 
   Williams's offense level based on witness intimidation and his 
   organizer/leader role in the offense; the government properly minimized 
   irrelevant communications, and the district court did not err in denying 
   defendant Campbell Jr.'s motion to suppress; no error in granting the 
   government's pre-trial motion to sever two defendants as the severed 
   defendants' statements were important in proving a conspiracy existed and 
   could not have been admitted in full if they had not been severed; 
   evidence was sufficient to support defendant Campbell Jr.'s convictions 
   for conspiracy to distribute cocaine and crack and possession of cocaine 
   with intent to distribute; the court did not abuse its discretion by 
   denying defendant Carter's motion for a buyer-seller instruction as it was 
   not supported by the evidence; evidence was sufficient to support 
   defendant Carter's conviction for conspiracy and possession with intent to 
   distribute; defendant Carter's sentence was not substantively 
   unreasonable; Campbell Sr.'s requests for multiple-conspiracy and 
   buyer-seller instructions were properly denied; evidence was sufficient to 
   support Campbell Sr.'s convictions for conspiracy and distribution of 
   crack and cocaine.
