Just looking at the press release for the series, and this comes up: "The series also is expected to touch on white privilege, as Dahmer, a clean-cut, good-looking white guy, was repeatedly given a free pass by cops as well as by judges who were lenient when he had been charged with petty crimes."
Colin is playing a guy named "Chazz". I don't know enough about Dahmer, but I'm assuming this is a fictitious character. It could be that Dahmer was aided by certain people, and perhaps Colin's character could be one of them. Or he's just a victim.
Either way, I don't really care about the show as I'm not into true crime stuff, but I hope we get some skin in a way that's not bleak.
