Most of the main characters, other than Huang (who was often portrayed as being "antagonist for the episode" despite being in the right), were this from season 5 onward on Law and Order: SVU, especially Benson and Stabler.
There was one episode where a victim who was being stalked and repeatedly raped by the same man didn't want to make a report because she was frightened of what he might do to her if he found out. Benson's solution was to basically stalk the girl and, if I recall correctly, pulled a gun on her at one point after the victim bought an illegal firearm to protect herself, until she managed to browbeat her into cooperating. Then, when they couldn't make any charges stick to the perp for some bullshit reason, all four of the main SVU detectives started stalking the perp day and night, even showing up at his office events to casual announce that he's a rapist, presumably neglecting other cases to pursue one where the victim didn't even want to file charges.
Then there was the episode where a kid (who was around 13 or so) came into the station to confess that he was having pedophilic urges and wanted help controlling them so he wouldn't end up harming anyone. Instead of being praised for being brave enough to come forward and ask for help, the detectives treat the kid like shit and basically tell him that he's a monster. They also did some investigating to make sure he hadn't harmed his younger bother, which was certainly understandable, but crossed the line again when they pretty much told everyone in the kid's life that he was an incurable monster. Then, instead of getting the kid into counseling, they released him back onto the streets -- now with the stigma of "monster" and "pedophile" attached to him -- and the kid ended up molesting his younger brother. Big shocker. Now, I wouldn't give the kid a free pass here, since he chose to act on his impulses, but it didn't exactly help matters that the detectives treated him like shit, piled a ton of stress on top of what he was already dealing with and then sent him on his merry way instead of, you know, actually trying to help him.
And of course, there were all of the times Stabler beat the crap out of suspects with no repercussions and even sent one guy into a psychotic episode to get information out of him, or all of Benson's "holier than thou" moments, or the various prosecutors suddenly getting a bee in their bonnet over some random bullshit. It's no wonder that I stopped watching the show.
