You don't have to let anyone search your car or your phone. Them asking to look through your car or phone is with in thier right. Telling them "no" or "get a warrant" is with in your right. Lets not forget the fact that a lot of people ride around with stuff in thier car that greatly affects all of our safety. Guns and god only knows what else people come up with. Now please don't get me wrong, I love all of my guns and I'm not about to give them up, but I also don't ride around with them because A) its not legal and B) I might use them.
