I'm probably leaving myself open for a few burns here, but it's my first topic so please be gentle. Lets say I'm delivering a pizza, and a pedestrian thinking I'm driving too fast obstructs my path and stops me in the middle of the street. He then approaches me cussing and grabs me by the arm while I'm still sitting in my car. The man is well over twice my weight, and I'm now fearfull for my well being. Would it then be unlawful to implement a handgun as protection, and if so what options of defense am I permitted by law? Thank you for any help you can give me regarding this question.
