Well, part of the problem is a lack of consistent prosecution, so it's not a surprise that there have been little in the way of murder charges or convictions.

We've seen video of an officer shooting someone and then going back to his squad car and appearing to remove a gun from his bag and plant it on the victim. Carrying around a "burner" gun (in case you might need it) seems premeditated to me, but IANAL.
