Perhaps Washington is a ‘must retreat’ state. Dunno. Fortunately I live in Georgia.
Do you feel lucky, punk?
I don't know, it might just be a "don't chase the intruder down and shoot him in the back" state. I've heard there are a few of those.
WA is not a “must retreat” state....but self defense is an affirmative defense in WA. That mean he must prove he acted in self defense.
If the facts at the scene didn’t readily show it was self defense then he most likely would be arrested then bonded out, considering his age, at a pretty low dollar amount I’d say.
