Strawman. I'm not saying these individual idiots are using Uzis, or any fully auto weapon. But, if you want to convince yourself that there aren't compounds in the US that don't have a stockpile of these types of weapons, then fine. Do you want to see what a coordinated attack by any of these extremist groups would look like? I know that I don't. Fully auto weapons, armor piercing rounds, shredder shotguns, etc. are all game changers. When anyone talks about banning firearms, you will have to take away their weapons as well as those belonging to law abiding citizens. Strict regulation of firearms will work, to an extent, but there are still illegal types of weapons flowing into the country. And these groups aren't collecting them for target practice or deer hunting.
