I just want to say that I HIGHLY doubt that if you walked outside and saw some1 under your truck taking a cat, you would shoot them. I doubt you constantly carry a firearm ON you, and if it's somewhere in your house, again I DOUBT you would run inside, grab a gun, and shoot a human being to kill them in a bloody mess.
Most likely, you would either yell something at him, and if you have balls, confront him. Or confront him while your on the phone with the police. Or run inside and call the police and hope they come in time.
Your telling me you would catch them in the act, grab a pistol or shotgun, walk up to them while under the car, and pull the trigger at them, 1 or more times. Brutally killing him and probably committing one of the worse crimes in your area.
YOUR FULL OF CRAAP AND SHOULD / YOURSELF for trying to act like a sav.
