Unpopular take but odo isnt actually copaganda. Humanizing cop-adjacent characters is not copaganda. Using cop-adjacent characters to make viewers question the legal system and the roles they play in oppressive systems etc is not copaganda. A cop being a main character in a show is not copaganda.
He's also NOT A COP. The reason all cops are bastards is that the modern USA police system/state evolved from slave patrols and the like and only ever developed more layers to oppress more minorities harder, usually Black people. They do not stop crime or improve communities. They cause MORE violence. They exist for No Reason except to enforce systemic inequality and commit regularly scheduled violence on individuals and communities. It's an incredibly serious problem and you know what, absolutely none of it is solved or even helped by you being an asshole to teenagers on the internet about a fictional character who lives in a bucket so that you can make yourself look smarter or more progressive than them. Odo is goofy as hell. The whole show is goofy as hell. Thats why we love it. The judicial structure of DS9 has many extremely fundamental structural differences that set it faaaar, far apart from the judicial systems of the USA. Characters in the show stand up to him about his more coppish instincts. When they do, he backs down, and they are portrayed as right for standing up to him. He is regularly blamed by the writing for his role in the occupation and held accountable. His journey from oppressed person who participates in fascism and violence and respectability bullshit to person who treats the law as something easily breakable to AID justice rather than dictate it, and who fights for the liberation of others at the cost of his own life is literally the opposite of copaganda. His extreme sense of actual justice typically wins out over his love of order and the law. Yeah, he still has moral issues, especially before the end of the show. Yeah, he does some pretty fucked up stuff. But that's still not copaganda, nor does it make him a cop. It makes him a very complex guy who's kind of a bastard but who also is constantly fighting a very difficult battle to not be a bastard. A lot of his character arc actually has very little to do with his cop-adjacent job and more to do with personal identity, cultural identity crises, learning how to allow yourself to be loved, learning how to make friends and why we do it, etc.
Odo is a complex character who makes us ask ourselves questions about our own legal systems, about fascism, about personal responsibility in oppressive systems, about the levels of oppression and how oppressors use them to leverage the oppressed against each other. But ultimately, he's not a cop. And even if he is, the way he is written is explicitly NOT copaganda. You're not smart or cute for not knowing what copaganda is and being constantly rude to strangers about Boneless Joe being their fave. Calm down
