Hopefully, the Second Amendment will help decent people keep this kind of commie crap under control once it begins here. Thank God and the Founding Fathers for the Second Amendment.
There have been a numerous comments to the same effect by Freepers over the last few days. I may be wrong about this, and the various outbreaks may have been imperfectly reported here in Britain: but in the sporadic riots in the U.S. which have occurred in my (fairly long) lifetime, I don't recall the Second Amendment being widely applied in practice. Shooting of rioters by police or the National Guard? Certainly. But shooting of rioters by ordinary citizens? If that's happened on a widespread scale, that news certainly hasn't crossed the Atlantic.
The second amendment does not protect you from evildoers.
Your god given rights to self preservation do that, using such force as you need to effect that protection.
The second amendment merely places into print that the US Gov't cannot infringe upon that pre exiting right.
