   U.S. Court of Appeals Case No:  03-4035
   District of Nebraska   
   [PUBLISHED] [Smith, Author, with Beam and Colloton, Circuit 
   Judges] 
   Criminal case - criminal law. District court did not err in permitting 
   police officer to provide expert testimony regarding drug conspiracies in 
   the Omaha area and typical drug record-keeping procedures as the 
   officer's experience and training qualified him as an expert, and his 
   testimony was relevant and probative; defendant had adequate notice of 
   the expert witness's qualifications and the nature and scope of his 
   testimony; applying Pirani's plain error analysis, defendant was entitled 
   to Booker relief as the record was adequate to demonstrate a reasonable 
   probability that the district court would have imposed a lesser sentence 
   under an advisory guidelines scheme.
