Not really - I just really don’t get how making a bomb can be considered to be a non-violent act. The bombmaker may not be the same person as the one detonating it, but they’re all part of the same process. Maybe it is a little snarky, but using “bombmaker” as an example of non-violent KKK activity kind of deserved it, I’d say.
Again, this statement doesn’t seem to match reality. Groups like this like to have a veneer of respectability and have been infiltrating the police since they started (pdf). There is also plenty of evidence that racism is tolerated among certain groups, and several civil rights acts have been enacted to combat this. The 1964 Civil Rights Act came in the wake of actions by KKK members in positions of police authority to attack civil rights:
When Schwerner, Goodman, and Chaney, a young black man, were coming back from a trip to Philadelphia, Mississippi, deputy sheriff Cecil Price, who was also a Klan member, pulled them over for speeding. He then held them in custody while other KKK members prepared for their murder. Eventually released, the three activists were later chased down in their car and cornered in a secluded spot in the woods where they were shot and then buried in graves that had been prepared in advance.
When news of their disappearance got out, the FBI converged on Mississippi to investigate. With the help of an informant, agents learned about the Klan’s involvement and found the bodies. Since Mississippi refused to prosecute the assailants in state court, the federal government charged 18 men with conspiracy to violate the civil rights of Schwerner, Goodman, and Chaney.
Bowers, Price, and five other men were convicted; eight were acquitted; and the all-white jury deadlocked on the other three defendants. On the forty-first anniversary of the three murders, June 21, 2005, Edgar Ray Killen was found guilty of three counts of manslaughter. The 80-year-old Killen, known as an outspoken white supremacist and part-time Baptist minister, was sentenced to 60 years in prison.
Another reaction to racist abuse of power by US police, who again somehow managed to slip through and be fully acquitted:
