Steve Sadly this happens almost daily. I know people that have lost their pensions, shields, and even there freedoms for doing things that what we would normally consider within their job description.
There needs to be some changes from the top down then if that is the case.
Hell if I was on the street and saw people doing that to cops, they wouldn't have to worry about arresting the person because I would take the person down myself and they would have to arrest both of us.
