So someone my dad works with got a flat tire on the way home from work recently. While he was working to change it a cop pulls up behind him. The guy thinks the cop pulls up to make sure he's ok or help but the cop came up and asked for license and proof of insurance. The cop goes to his car and comes back and asks 'where's the gun?' (he has a permit). The guy says he doesn't have one on him and the cop pushes the issue and asks to search the car. Another patrol car pulls up and they search the entire car and find nothing. They leave but by that time the guy has to change the tire in the dark. This happened in TN. This of course raised some questions: What right does LE have to ask for anything in this situation? They have to have a reason to pull someone over but what if they're already stopped like in this case? What about searching the car for a gun he has the right to carry? Is that an illegal search? What if they found one?
