After you're acquitted, make sure you get a shark-toothed CIVIL attorney, because you will most probably be sued by the perp's family.
Actually that depends on the state you live in and where the shooting takes place. In Delaware there is a law that says you may only be sued if you are convicted. If Self defense is ruled justified, or you are no billed, or not arrested, the perp CANNOT SUE YOU period. Thats Factual information.
What state do you live in Keltyke? Do you know the law in your state???
