Martin Luther King Jr. was stoned (a thrown rock struck him in the head) during a March he lead (of about 700 people) in Marquette Park on Chicago’s Southwest Side. The civil-rights leader and his supporters were in the white ethnic enclave to protest housing segregation practices. Approx 30 others were injured along with Dr King. He later explained why he put himself at risk: “I have to do this–to expose myself–to bring this hate into the open.”
