Prosecutors defend urging no charges in Tamir Rice shooting
McGinty said the Department of Justice's U.S. Attorney's manual says a prosecutor must tell a grand jury when substantial evidence refutes the guilt of the target in the investigation.
A grand jury announced on Monday that no criminal charges would be brought against the white patrolman who shot Tamir in November 2014.
Two Democratic state lawmakers in Ohio said Wednesday they plan to propose legislation that would require at least two outside law enforcement officials to conduct investigations when a police officer uses deadly force.
