Here in Michigan we have to inform the officer when we're stopped that we have a CPL and whether or not we're armed. (or at least that's my understanding) Last week my wife and I were driving back from Florida on I-75 and she was stopped driving my truck, the FHP trooper made a passenger side approach and it dawned on me I had no idea if a: I had a duty to inform the trooper that I was armed if 'I' was stopped but since my wife was driving technically 'I' wasn't stopped and b:since she was at my window did I have to inform her I was armed? My question is since I wasn't stopped was I even supposed to tell her? (I did, she seemed a little miffed) I'm just curious as to how or what do you expect the passenger to say if he or she is armed and if the fact it was my car and she was at my window made any difference. Had she made a drivers side approach I would have just kept my hands where she could see them and STFU but like I said she was looking at me and tapping on my window at the initial contact so it sure seemed to me like 'I' was stopped. Thoughts?
