You likely already know that, should you be stopped for driving drunk, your arrest will be captured on audio and video recordings. But, the Washington State Supreme Court ruled today, the arresting officer has to first tell you he's preserving your every slur and stumbling move on tape. As a result, four DUI cases have been remanded to the trial courts for new hearings. "Although we conclude that conversations between traffic stop detainees and police officers are not private conversations," the high court said, "we hold that the privacy act requires that officers inform detainees that the officers are recording their conversation." The court assumes that drivers won't be too drunk to hear such warnings.
