"Let's kill all the white people," one person said. "[K]ill all white people," another person added.

Immediately after the announcement, violence broke out as protesters attacked police cars and looted stores. A photo posted at the Gateway Pundit showed a police car on fire, and other photos showed police cars being attacked. Fox News also reported that shots were heard after the announcement.

Agitators, including revolutionary Communists and black militant groups, called for violence if Wilson was not indicted. A flyer passed out by the Revolutionary Communist Party said "Amerikkka (sic) must be brought to a halt" if Wilson walks, the Gateway Pundit's Jim Hoft said. Hoft also said a group that put together a video threatening to kill people were spotted in Ferguson. A group calling itself the "RbG Black Rebels" encouraged supporters to "pick a target" and act "solo." Earlier in the month, the group posted photos of ammunition and encouraged others to stock up, saying that a 7.62 mm bullet "will solve a lot of problems."
Earlier in the day, St. Louis Post-Dispatch reporter Paul Hampel said he was warned of violence. "I am not racist. But you're not safe here," one protester told Hampel.
