Remember: if a cop asks “do you know why I stopped you?” (Which, per this article, cops in some places are not supposed to do now, not there’s there’s any consequences at all) - the answer should always be “What did you stop me for?”
Close your mouth to prevent self incrimination and let them do the talking.
