Hoo wee. This is the kind of thing public unions get ya. It should be "you do dope on duty and do something crazy like this, you never 'bear the sword' on our behalf again. Period."
It doesn't take long for the bad cops to learn they can do whatever they want, and the city will cover it up.
Don't ever let anyone tell you police abuse and corruption is covered up from the bottom up. The cover up comes from the top down.
