As a former Cop I do not feel right about Tamir Rice!

When the going gets paranoid the paranoid become cops. I mean, really. Shot off a swing? Lawmen are taught the Use of Force Continuum. What happened with 'show me your hands'? What about taking a position of cover? Caliber Press anyone? I can already hear it from the other-side. How the cops have a tough job blah-blah-blah. I was a cop for too long to not know the difference between good police work and not so good police work.
