Police departments are notoriously defensive and insular. Their special status as the sole legitimate users of force has contributed to a mindset of “them against us,” which has engendered a culture of secrecy.

Entrenched practices that serve no legitimate purpose, failed policies, implicit and explicit racism among the rank and file, and a culture of hostility toward the public must be rooted out.
