   U.S. Court of Appeals Case No:  11-1999
   U.S. District Court for the Southern District of Iowa - Davenport   
   [PUBLISHED] [Riley, Author, with Beam and Bye, Circuit Judges]
   Criminal case - criminal law and sentencing. Officers had probable
   cause to conduct a Fourth Amendment seizure based on defendant's
   erratic driving and traffic violations; having made a lawful stop, officers
   were justified in detaining defendant for a time reasonably necessary to
   conduct a limited investigation; drug dog sniff did not extend the scope or
   duration of the seizure and did not violate the Fourth Amendment; the
   district court did not err in finding that, on balance, defendant's behavior
   leading up to and including the warrantless search of his home was
   consistent with a finding that he voluntarily consented to the search;
   district court did not err in calculating drug quantity.
