In this case a traffic stop was made (bicycle without a light at night). The bicyclist was in possession of a firearm and the officer removed a bag the bicyclist revealed contained a firearm from the bicyclist’s shoulder and put it on the hood of the car. The firearm apparently was unloaded and therefore was not a violation of Utah's concealed carry law. The officer then ran a warrants and records check and found a prior conviction for drugs and several other arrests without a conviction. The officer then spoke to the bicyclist further, and the bicyclist admitted he was a current drug user, which prohibits him from possessing a firearm under federal law. The court ruled the officer had no “particularized and objective basis to suspect that he might be engaged in criminal activity.” The court ruled the officer extended the stop in violation of the 4th amendment and suppressed the evidence.
