When persons unknown come crashing into one's home, the innocent homeowner is perfectly justified in using lethal force. It should never even get to a jury.
I'm waiting for the day when the cops break into the wrong house and get blown away by the homeowner. Home owner would walk if I was on the jury.
Unless, you're a cop. In which case, if they made a mistake or not, if you shoot one of them, you're in trouble. If they shoot you, oh well...sorry. Things happen.
