You probably shouldn’t.
We’re sure that most police officers are intelligent and principled individuals, but the fact remains that when a small group is given extraordinary powers in society, “trust” is not really something that should be operative. Blind trust in authority is madness; the only way to survive is to create a rigorous oversight structure that makes it all but impossible for the empowered to engage in the kind of criminal behavior that is unfortunately so common in law enforcement the world over, and that we see exemplified in Atlanta in the story linked above.
