Here's an even more novel idea, apparently. Have police follow procedures relating to deadly force and don't try and lie their way out of it.
DuBose was of no threat to the officer or anyone else. There is no evidence he was armed. There is no evidence he tried to harm the officer. Running away from a stop shouldn't be a capital offense. The officer should have called it in and then get back in his car and pursue. He had no justification in shooting him.
A high speed chase of a drunkard is not an option, is it?
