Changes? Great. But are we supposed to believe that because of improper training, bullying and abusing people with "real or perceived" mental illness was ever considered okay? Does being an ass to a person, setting them off so you can use the power you want to use a valid strategy for dealing with anyone?
Promise of change is better than nothing. However, I refuse to believe that training or policy did not allow officers to use common sense. We've covered this month an old woman pulled from her car, a petite nurse body slammed into the ground, and learned that police set up the Occupy movement and enticed them to turn criminal so they could be busted.
We need cops to be the good guys. It's not easy, but if it was easy everyone would do it.
