As a good friend, whose advice I value highly, said to me; "if you draw your gun it had better be smoking."
Sadly, that’s probably the case.
You’d probably be in some trouble for “brandishing” even if you felt your life was being threatened.
Really, if the lefties want to reduce the number of self-defense shootings, they should change the law so that someone cannot be charged with a crime for deterring an attack by letting them know you WILL shoot them if they press their attack.
