Give me all the gritty thrillers and crimes

Good day to everyone :)

I am on a thriller hunt at the moment. I want something that will make me angry and frustrated but will also keep me engaged. I love well-made thrillers where they discuss problems in societies (rape, serial crimes, bullying, violent crimes etc...) and they try to catch the bad guys. Now I know this is a popular genre but I feel like I have watched the good ones. I love seeing a team of people working together to solve the cases and I would appreciate it if it's not necessarily tangled up in politics because most of the time these tend to overshadow the whole premise from where the show began. I will list my favorite shows from this genre for reference!

Hope you guys have something for me (I don't need romance in those but I am not opposed to it as long as it works)
