Discussion going around the office that is interesting. Failure to knock and announce has been in effect from the Supreme Court since 1995. But if someone comes busting through the door are you going to hesitate to fire? Especially if they are dressed all in black? I think personally I am going to get shot and at the very least go to jail for shooting an officer. If I dont get a knock and announce, and someone comes through my door, well I would like to believe for my family's sake that I would not think and I would respond by shooting the first one through. I would feel bad but, but where would I stand legally as I have never heard of this occuring.
