I have been threatened by a radical muslim group. It is my working assumption that anyone wanting to 'disappear' me or forcibly enter my home must be a terrorist. Worse, they are possibly terrorists posing as police officers. I'm not a criminal, so no government officer has any reason to try to 'disappear' me or execute a no-knock warrant. Anyone who does would qualify as terrorists, especially since American soil has been designated as a battlefield in law.
The dumbass Congress didn't think it through. Anyone breaking into anyone's house is a terrorist now. And everyone is legally entitled to resist them. That's what a battlefield is. Defining the homeland as a battlefield gives everyone the right to defend against terrorists posing as police or military. It is a defense grounded in law.
