You are handicapped. You go out your front door. You see your teenager taking a beat down from a mob. You yell but no effect. You cant run down there and even if you did you could not help due to your condition. You draw your legal pistol and fire one round into your lawn. The mob runs off. Your kid is saved.
How many years should you get in prison for firing that shot?
You can walk, but not to good. You have to use a cane due to injuries from Viet Nam. You walk out of WalMart after dark. The parking lot is well lit. You get charged by a mob, they are yelling and screaming. One is behind you and he hits you so hard you see stars and cant breathe. When the mob is in hand reach of you, you manage to draw your legal .45 auto. They scatter. You wonder what would have happened if they had not stopped. You wonder what would have happened if you did not have your 45. You wonder what would have happened if you had to shoot one of them. They would have run off, leaving you with a wounded or dead unarmed (possibly) "victim". You thought of firing a warning shot in the air but are glad you were not forced to. You call the police right away and report the incident.
