I think this officer has/had seen enough of the black/white confrontation results and the circus that accompanies it especially if the media and the politicians and the special interest radicals decide here is another golden opportunity.

He either figured with the girl screaming and a camera just a few feet away he may have realized what was going to come from the media/poitical circus to follow.

Maybe he talked offline to his boss and then decided life is too short to become another Ferguson.

Or he had previously made up his mind this new black/white BS media circus is not worth what a cop has to go through and threw in the towel........like many are in how the currently do (or should say not do their jobs).

Where are the white protestors to come to his aid?
