The shots were fired hours after Ferguson’s mayor announced the resignation of Police Chief Thomas Jackson in the wake of a scathing federal government report alleging bias within the city’s police department and court system. Before the shooting, some at the protest were chanting to show they weren’t satisfied with the resignations of Jackson and City Manager John Shaw earlier in the week, the St. Louis Post-Dispatch reported.

A 32-year-old officer was shot in the face and a 41-year-old officer was shot in the shoulder, St. Louis County Police Chief Jon Belmar said at a news conference. Both were taken to a hospital, where Belmar said they were conscious, but he described their injuries as “serious.”
