Just like JFK's assassination set off the 1960s triumph of the Left because of the media's instant assumption that some rightwing redneck in Dallas had done it. (It eventually turned out that the shooter had defected to the Soviet Union, where he met his wife, who was then living with her uncle, a colonel in the secret police, but who remembers that?)
Well, it turns out that today's shooter was named Jiverly Voong. So, it's just another immigrant mass murder story that will disappear down the memory hole after some ritual calls for gun control. The VDARE.com blog has the details.
