What state is this in? Unless it can be PROVEN that my life or someone else's was in immediate jeopardy - I have no authority to shoot an unarmed person outside of my home. I will be charged.
If it is shown that a perp was unarmed, and I shot the perp while he was robbing a neighbor's home - and killed him - I will be charged with murder.
Those are facts
at least in my state and is covered extensively in any CCL course you take. The threshold for legally using deadly force, is very narrow. Self defense has to be demonstrated - unless the perp is INSIDE your own home.
I live in the Hornet’s Nest. Should be easy for you to figure out where I live by first sentence.
