Let's see, a Flagstaff police officer shoots an unarmed man. The shooting is investigated by the Coconino County Sheriff's Department, which shares a building with FPD and all the officers and deputies are friends. Does anybody else see why this is not an impartial investigation?

Why not have the Arizona Department of Public Safety do the investigation? Chief Treadway wants to be transparent, here's the best place to start. Let an outside agency do the investigation, so it can truly be impartial. Or is Treadway afraid of what they may find?
