ok this is my question. first off as a disclaimer i want to just say that i dont plan on going trigger happy on anyone or waving my handgun around for no reason. i want to know what the legalities are for carrying a handgun in my car for personal defense. also say for instance someone came up to my car or where i was parked and tried to cause me or anyone of my passengers bodily harm, what can i do? could i legally draw my gun detain him and then call the cops? and wait for them to come? i am asking this not because i think it will happen or anything but to at least be mentally armed as to what my rights are to protect myself when dealing with this type of situation.
