I would not have wasted my time demoting people they would have the choice of being fired or putting in their resignation papers effective immediately. When you were the badge and take that oath, it's that oath that says something. When you have breached the trust of the people you have sworn to serve and protect then it's truly time for you to choose another line of work. The supervisor of the department wouldn't been given a choice she would have been terminated because how can you call yourself a supervisor when you didn't know what was going on in your own department. That says a lot about your management skills. Then to cover your backside you go to Internal Affairs as if you had nothing to do with it. Your Division, your mess. Apparently the chief must have promoted someone and put them in a position of leadership that they weren't ready to accept. This is truly a blackeye for the WPD.
