   U.S. Court of Appeals Case No:  09-3453
   U.S. District Court for the Northern District of Iowa - Cedar Rapids   
   [PUBLISHED] [Smith, Author, with Bye and Beam, Circuit Judges]
   Criminal case - Criminal law and sentencing. While the district court
   erred in excluding testimony from an inmate to impeach the testimony of
   an inmate cooperating with the government because the testimony was
   extrinsic evidence of a prior inconsistent statement, the error was
   harmless; evidence was sufficient to support defendant's conviction for
   possession of child pornography; no error in applying enhancements for
   age of the minors depicted in the images or for possession of material
   depicting sadistic or masochistic conduct; no error in imposing an
   enhancement for obstruction of justice based on defendant's perjury at
   trial; no error in imposing a criminal history point for a uncounseled prior
   misdemeanor conviction as the conviction did not result in a sentence of
   imprisonment.
