Shootings like Aurora and Sandy Hook happen very quickly. The idea that Obama storm troopers flying in on helicopters could do anything to stop them is absurd. Obama is using the shootings as an excuse to ramp up martial law, and to hear the sheeple bleat thank yew as he does it.
The best way to stop shootings is to keep them from being planned in the first place. Shooters almost always target gun-free zones, so eliminate gun-free zones. Schools need security -just like banks and other business do. Lefties apparently think that our children deserve less security than used car parts at the junk yard.
