Let me see if I have your position correct.And you think the appropriate punishment is she be murdered in cold blood. You can whine all you like but the only person who suffered that day was an unarmed woman murdered in cold blood.
I have no regard for your morally fucked up opinions
If you, Yakuda, has security persons outside your home and a group of people attack that security and then break into your home while shouting things like "Kill Yakuda", the security can no longer shoot anyone even if one of that group enters the bedroom through a broken door where you might be hiding unless there is an obvious weapon on that person. That would mean you have also forfeited any defense where you could shoot someone unless they were visibly armed.
Congratulations for being against the castle doctrine.
