So let me bare a question, what do yall think would happen if daddy and his two sons loaded up with evil guns and set out to protect their property and business and it got ugly real quick. Someone tries to instigate a fight by throwing bricks, rocks whatever, that could be considered a deadly action, and they cut loose on the rioters there to burn.
Considering the current situation around there, I wouldn't worry about the law as much as having enough ammo. It'd be like stepping in an ant bed.

After you send the first round down range, you better be ready to shoot until you run out of bullets or time. It'll either be you or them. I am imagining a Benghazi situation, except in this instance, the only people who could feasible bail you out are your neighbors, or the ONE officer in your local PD with some sense of honor. Most will scatter on you.
