The Southern Poverty Law Centre, a US civil rights group, has some background information on the man arrested for shooting dead three people at Jewish centres in Kansas yesterday. Frazier Glenn Miller, 73, is a former “Grand Dragon” of the Ku Klux Klan who has served time in prison for operating an illegal paramilitary organisation.

The SPLC describes Miller as a “raging anti-Semite” and draws attention to his prolific use of a white supremacist website, the Vanguard News Network (VNN):

This isn’t the first time a VNN user has been arrested for violence. On January 17, 2011, less than 12 hours after posting on VNN, Kevin William Harpham placed an improvised explosive device concealed in a backpack along a Martin Luther King parade route in Spokane Washington. The lead sinkers in the radio-detonated IED were coated with Warfarin rat poison, evidently intended to increase bleeding. Had the device functioned, dozens of men, women and children would have been killed or injured. Harpham also distributed [VNN's newsletter] The Aryan Alternative.

Our research shows that racist killers are hiding among us in plain sight. A forthcoming two-year study by the SPLC will show that nearly 100 people in the last five years have been murdered by active users on another prominent racist website, Stormfront.org.
