Sadly if these departments do not start prosecuting these officers you are going to see increasingly more officers killed in retaliation. The police and politicians can preach calm and respect the law until they are blue in the face but eventually human nature is going to take over and it will be blood for blood.
I hate that it has come to this but either the police have to start policing their own and reigning this crap in or the public will turn on them and then all hell breaks loose for the police and the public. We need the police but we need those officers held to the same standards as they hold the citizens they are supposed to serve.
Revenue raising traffic stops will become evermore dangerous..
