I assume you're talking about Dixon? Early on, he's established as a racist good-old-boy; a caricature of a bad cop. Then we learn his Mom's also a racist *and* he can be equally horrible to white folks, too!

So what's the message there? An uncharitable reading could assume the movie's saying systemic police racism is an illusion created by bad officers who are equally bad to everyone.

But beyond that, the "turn" Dixon takes is so cheesy and unearned, it feels gross that we're asked to actually root for him after seeing what a piece of shit he is just minutes earlier.
