   U.S. Court of Appeals Case No:  08-3249
   U.S. District Court for the Southern District of Iowa - Davenport   
   [PUBLISHED] [Smith, Author, with Murphy and Shepherd, Circuit Judges]
   Criminal case - criminal law and sentencing. Evidence was sufficient
   to support defendant's conviction for possession of crack with intent to
   distribute; admission of a cooperating witness's written plea agreement as
   evidence of the witness's credibility is left to the district court's
   discretion, and its admission here was not an abuse of discretion; closing
   argument defendant points to as improper vouching was made in rebuttal
   to his comment and properly directed the jury to the provisions of the
   agreement; statutory mandatory minimum under 21 U.S.C. Secs. 841 and
   851 is constitutional.
