Read the whole thing:
On June 10, 2009, an elderly man entered the United States Holocaust Memorial Museum, raised a rifle, and opened fire, killing a security guard named Stephen Tyrone Johns. Two other guards shot back, wounding the gunman before he could end any more lives.
The killer was soon identified as James Wenneker von Brunn, an 88-year-old neo-Nazi. Von Brunn acted alone, but there was no shortage of voices eager to spread the blame for his crime. The murder was quickly linked, in a free-associative way, to the assassination 10 days earlier of the Kansas abortionist George Tiller. This, we were told, was a "pattern" of "rising right-wing violence."
