DES MOINES, Iowa (AP) — The Iowa Supreme Court has made it significantly more difficult for police to continue to ask questions or even ask for a driver’s license during routine traffic stops if there is no reasonable suspicion a crime has been committed. In a ruling Friday, the majority of a divided 4-3 court overturned a 30-year-old Iowa legal precedent that said officers could at least ask drivers to produce their license during routine stops.
