4 ex-cops charged in Tyre Nichols' death decertified from police work.

Three former Memphis police officers charged with murder in the beating death of Tyre Nichols have been decertified by the Tennessee Peace Officer Standards and Training Commission, preventing them from working at other Tennessee law enforcement agencies. The fourth officer surrendered his certification. The officers were found to be in violation of personal conduct, truthfulness, neglect of duty, excessive unnecessary force, and other violations. Three other former officers investigated in Nichols' death will have decertification hearings at a later date.
