But like anyone else "in uniform" they need, must have, good leadership.
It's said a fish rots from its head, and rotten leadership can corrupt the best of organizations.
Banal aphorisms aside, I don’t think the police “wish to mess” with ANYBODY.
What they WANT is to not have their boat rocked, like any other employee of the state. And like other employees of the state, they are not above using their position to “punish” those who “rock the boat,” but often with life changing consequences for the originator of their irritation. And this doesn’t begin to touch on what they will do to “civilians” who witness, and (God forbid) pursue redress for, incidences of actual malpractice on the part of police.
Furthermore, I have yet to meet a single working police officer that has, or will, repudiate the practice of lying to a “suspect.” Despite the decision of ANY court to the contrary, our Founding Father’s concept of “the presumption of innocence” can not be reconciled with willful deceit for the purpose of getting a person to incriminate themselves: by definition.
If you are “actively” concocting a lie to get someone to admit something, it is logically impossible to be “presuming” they are innocent. Again, by definition.
I could go on about other practices that are taken for granted, yet antithetical to “American” culture, values, and founding principles, both explicit and implicit, but this example should suffice to demonstrate the “patriotism” of professional law enforcement workers in this country is honorary, not earned.
