This combination of photos provided by the Hennepin County Sheriff's Office in Minnesota on Wednesday, June 3, 2020, shows Derek Chauvin, from left, J. Alexander Kueng, Thomas Lane and Tou Thao. Chauvin is charged with second-degree murder of George Floyd, a black man who died after being restrained by him and the other Minneapolis police officers on May 25. Kueng, Lane and Thao have been charged with aiding and abetting Chauvin. Minneapolis adopted a policy in 2016 requiring officers to intervene when colleagues are using inappropriate force. Yet three other officers at the scene failed to stop 19-year police veteran Derek Chauvin when he put his knee on Floyd's neck despite Floyd's cries that he couldn't breathe.
