"So I don't think some dude on his back porch with a .22 and 500 rounds is gonna do a whole lotta damage against a group that has full auto weapons, stun grenades, gas, night vision technology, etc, etc, etc."

Also, there is also the Battle of Athens, Tennessee to consider. The JPFO has it on their website.
