Dim Crims: Cops arrest 'Cop Killa'

Chicago police  have arrested  a man who has a tattoo just below his  left eye that says “Cop Killa.”
There is no evidence that he ever killed a cop, but police say they have the recordings of repeated 9-1-1 calls during which  27-year-old Antonio Hammond threatened to shoot and kill police officers in the Odgen District.
