Right-wing media and the fringe: A growing history of violence (and denial)

This week, the country's attention was captured by the horrific shooting at the U.S. Holocaust Memorial Museum, allegedly by James W. von Brunn, an 88-year-old man with ties to white supremacist and anti-Semitic organizations. The fatal shooting came just two months after an April 7 Department of Homeland Security report detailing potential increases in right-wing extremism.

As Media Matters for America documented, the DHS report was immediately and vehemently rejected by numerous conservative commentators, such as Lou Dobbs, Rush Limbaugh, Sean Hannity, Michelle Malkin, and David Asman, who portrayed it as an illegitimate and politically motivated assault on conservatives. (Media Matters Senior Fellow Karl Frisch puts the attacks in even broader perspective here.)
