   U.S. Court of Appeals Case No:  05-4060
   Eastern District of Missouri   
   [PUBLISHED] [Colloton, Author, with Loken, Chief Judge, and Melloy,
   Circuit Judge]
   Criminal case - Criminal law. District court erred in granting
   defendant's motion to suppress evidence seized during a drug
   interdiction checkpoint stop; district court erred in finding
   that the police officer's request for defendant's identification
   and registration papers, and his brief retention of the documents,
   constituted a seizure; the officer's subsequent actions - asking
   defendant to exit his vehicle, subjecting defendant to a patdown
   and informing defendant that if he did not consent to a search
   the officer would call a drug dog - did amount to a seizure, but
   the officer had reasonable suspicion of illegal activity sufficient
   to justify an investigative detention and a dog sniff of the vehicle.
