Never get out of the car if unarmed. It is your best weapon.
Don’t get out of the car unless you are armed and your clip is adequate for the situation. Nine shots into a crowd of 50 - 200 angry youths may only make them madder. After you’ve emptied out your clip, your survival may be slim and none.
Yeah getting out of the car? Bad idea. Getting the hell out of Dodge? Excellent idea especially if you have the wife and little children with you.
