Unfortunately for the MSM the perpetrator turned out to be a completely loony admirer of the Communist Manifesto and a total pothead to boot. Also, Congresswoman Giffords was in favour of gun ownership. Given that, in the States, Liberal has come to mean "Rabid Left-Winger", it is nice see them hoist on their own petard!
It was a truly great American, Thomas Jefferson, who said, "When a government is scared of its people, that is democracy. When a people is scared of its government, that is tyranny!". We could do with a Thomas Jefferson in the UK right now!
