You can bet your ass I would empty a clip on anyone entering without law ful authority, I don't give a damn if he or she says they are the President of the United States of America!
Not happening!
Remember, if the cops violate the fourth to get evidence to use against you, the court will throw it out.
This isn't a Fourth Amendment case anyway.
The judges are nutballs.
What does the Castle Doctrine say? To me it says if it's dark and somebody is kicking in my door I get to lay 'em out with machinegun fire if I need to. Doesn't matter if they are cops or the neighborhood kids.
ON THE OTHER HAND if I know they are cops, or children seeking candy, the burden of proof changes and I need some other reason than simply fear for my life and limb to shoot 'em down.
You have a case here where the perp already admitted he didn't live there, and he knew these guys were cops. They were invited in by the woman living there.
Do you realize that screaming FOURTH AMENDMENT in a case where the cops responded to a woman's call for help makes you sound so Shi'ite and Islamofascistic ~ bet your women folk just melt at your touch.
