"Mr. Cruz was directing traffic near a birthday party when three officers drove by and thought he had insulted them. They told Mr. Cruz he was under arrest and wrestled him to the ground, during which time one officer shot himself in the leg.The officer then repeatedly shot Mr. Cruz, who was lying on the ground, in his head and body before they drove off. An internal investigation cleared them of misconduct. But after a video of the incident surfaced in the news media, one officer was convicted of murder. It emerged that seven complaints had been filed against him, but had been largely ignored."
