Sorry, but I don't think this is even remotely true. Cops overwhelmingly don't testify against other cops. And, in my book, cops that put up the blue wall of silence are bad cops. Not as bad as the cop they're defending -- I don't mean to equate them -- but still bad. While something like that may exist in some engineering-heavy workplaces (I've heard stories but never seen it), it's nowhere near as common or institutionalized.
