there is no reason for cops to be coming into my home
I have no reasonable expectation of such happening to me in my home.
Therefore I will respond as if it's a lethal threat, which if it is an actual law enforcement entry in to my home, it will get very bad for me in very short order. In short, I will probably be dead.
As they say, that's life. My family may be able to pick up the pieces and move on, with a nice compensation check, but I will be dead and buried. I only hope that, law enforcement or not, if you attack my home through error, I take a few illegal entrants, or what I presume to be illegal entrants in to my home, with me to the gates of Hell.
