So your afraid of a guy with a gun but people shouldn't be concerned that you were in a car that hit them and you get out with your gun on your hip?
Thats why some have made the argument tha if everyone carried guns around there would eventually be a gunfight over a misunderstanding.
Think about that for a while.....this whole scenario that you have laid out.
Re-read your original posts......you were concerned that he reached back into the car......you got concerned even when you didn't even see a weapon.
What if he did reach in and get his gun and you saw him put it in his pocket? You still ok with that? Ever here of a bump robbery or a car jacking that started out with a "Bump" from behind.
It was real popular at one time.
