I just don't think it would come to that. I mean, I look at at it this way: I figure at least half of the military is going to to go AWOL, rather than violate their oath to uphold the constitution. This will probably be entire brigades. Second, if the poop really hits the fan, it's going to be anarchy anyway. The military and LE aren't going to be going door to door collecting and searching for weapons, they are going to be barricading, and protecting civilians who can't take care of themselves.
I still say, get out of town, and you'll do okay. You just have to have the mentality that you are going to be self sufficient. Stay in small groups and don't present yourself as a threat.
