I mean Wei Shen being a cop works pretty well for the story imo.

SPOILERS

It's implied that Wei is barely even a cop, and just did all of this so he could kill Dog Eyes. I like the way the game positions the police as villains in the story. Most of the Sun On Yee are portrayed to be good to morally ambiguous, while the cops are shown to be more questionable than the Sun On Yee. Whenever Pendrew starts moving in on the Sun On Yee, Wei is shown to side with his people to hide shit. He's a cop, but he's shown to have entirely his own motives that are entirely extrajudicial, Wei is the least corrupt cop but he's shown to still be corrupt as fuck. Dog Eyes being hung on a meat hook is a worthy ending for such a piece of shit and Wei has every right to do it. But it's objectively an abuse of Wei's police power. I like their portrayal of police corruption, whether it was intentional or not
