Wisconsin police can legally draw blood from unconscious drunken drivers without a warrant, the state Supreme Court ruled Tuesday. The justices ruled 5-2 that drivers automatically consent to a blood draw when they drive on Wisconsin roads. If drivers drink themselves into unconsciousness, they forfeit any opportunity to withdraw that consent. The ruling stems from a case involving Gerald Mitchell, who was arrested for drunken driving in Sheboygan County in 2013. Mitchell passed out after he was arrested. Polcie took him to a hospital for a blood draw. Mitchell argued the draw violated his constitutional rights to eb free of unreasonable searches and seizures. Mitchell’s attorney, Linda Schaefer, said she hands read the ruling Tuesday morning and had no immediate comment.
