A Homeland Security Department analyst and a 2009 report he helped produce on right-wing extremism is receiving increased attention after Wade Michael Page, a 40-year-old white supremacist and military veteran, shot and killed six worshipers and wounded others, including a police officer, at a Sikh temple in Wisconsin.

Daryl Johnson worked for the Homeland Security Department and put together a report that was leaked to a “conservative radio shock jock” in southern California named Roger Hedgecock. The report, “Rightwing Extremism: Current Economic and Political Climate Fueling Resurgence in Radicalization and Recruitment,” which the shock jock made public in 2009, set off a conservative media frenzy.
