Officer who Shot Tamir Rice Was Regarded as Unstable

In the aftermath of non-indictments for police killings in Ferguson and New York, Attorney General Eric Holder's in Cleveland, Ohio today.  He announced a consent decree that will lead to federal monitoring of lethal force by the police in that city. Holder says history shows “meaningful change” is possible in Cleveland, as it has been in other cities.  Meantime, since the incidents the Justice Department investigated, there's been another case in Cleveland that's caused public outrage.  A white officer named Tim Loehmann shot and killed Tamir Rice, a black 12-year-old who was playing with a toy gun in a public park.
