Using a drug-sniffing dog in a completed traffic stop, in the absence of any reasonable suspicion to do so, is unconstitutional, the Supreme Court ruled yesterday in a 6-3 opinion.
Officer Morgan Struble pulled Dennys Rodriguez over for veering onto the shoulder, then jerking back onto the road. Rodriguez had a valid driver's license and no criminal history. After writing Rodriguez a warning ticket, Struble asked for permission to walk his dog around Rodriguez's car. It wasn't actually a question, as Struble did so even after Rodriguez said no. After two passes around the car, the dog alerted to drugs, and indeed, a search of the car revealed methamphetamine.
