In August 2012, a white supremacist fatally shot six people in a mass shooting at a Sikh temple in Oak Creek, Wisconsin. It was the worst race-based attack in the U.S. since the KKK bombed the 16th Street Baptist Church in 1963. Pardeep Kaleka is the son of one of the victims. The man who killed Pardeep’s father was part of the largest racist skinhead organization in the world, which was founded by Arno Michaelis.
