Last week the  U.S. Justice Department announced a civil-rights investigation into possible misconduct by Clevelandpolice. The mayor stood with his police chief and public safety director alongside U.S. Attorney Steven Dettelbach and Thomas Perez, head of the U.S. Justice Department's Civil Rights Division, as the two announced a federal investigation of allegations thatCleveland officers routinely use excessive force in the line of duty.

Besides examining the conduct of front-line officers, federal investigators will look at howCleveland police are trained, supervised and disciplined. “We will peel the onion to its core,” promised Perez.
