The sheriff who oversees one of the nation's most crowded jails has voluntarily released video showing half a dozen incidents of excessive force by deputies at the Cook County Jail in Chicago.
The videos show violent encounters between jailers and inmates. In one, three officers drag an inmate with blood spattered on his shirt through hallways to a cell.
Another shows an officer throwing a punch during a take-down of an inmate.
Thirteen officers were disciplined over the incidents.
