Wednesday's mass murder of black churchgoers in Charleston, South Carolina is the most high-profile example of white extremist terror in the United States since Timothy McVeigh killed 168 people in Oklahoma City on April 19, 1995. But though not each incident makes national headlines, a tally kept by the Southern Poverty Law Center indicates that the murder of law enforcement officials and innocent civilians by racial supremacists, anti-government paranoiacs, and other believers in white fringe movements has been depressingly common in the two decades since Timothy McVeigh's attack. Below (taken from SPLC's records and confirmed by outside news accounts) is a list of 32 deadly attacks since Oklahoma City—comprising a total of 70 victims—carried out or believed to have been carried out by white extremists.
