alt Hacker NewsNearly every police procedural does.
Every one that I've seen (which is several, but a long way from comprehensive—there are a hell of a lot of them) features the main characters frequently and deliberately violating suspects' rights, both Constitutional and otherwise, in order to get the evidence that they "know" has to be there, with widely varying degrees of ostensible justification being provided.
FWIW, The Wire strikes me as very much not “copaganda.” It has the rights violations you describe, among other things, but the thrust of the presentation seems to be: “this is real, this is routine, and this definitely is not working.”
