There was one case in Spokane WA a couple years ago where a domestic abuse victim, (at least that is she tried to discribe herself) shot and killed her husband and tried to claim self defence. Not, the jury came to the conclusion it was premeditated murder (I agree)
WA does not have a SYG "law" as such...it has court opinions that effectively give us SYG. However,,,
In this ladies case she went to the ex-husband's home, and shot him in the back...not exactly what you would expect in a self defence situation...no?
