Who writes that notice? A coalition of the foot soldiers who are doing the actual arrests, or some high-minded politician sitting behind a desk? Because that politician can't actually make promises about the behavior of the police. De Blasio has been denying that well-documented cases of abuse have happened, and saying that if such a thing were to happen, it'd surely be punished. We've yet to see any accountability for NYPD.
Statements are nice. Actions matter.
