In striving to make Ebbing feel like a lived-in place, rather than just an idea of one, Three Billboards treats racism like it’s just another quaint regional detail — part of the local decor. Here’s the gift shop, here’s the bar, and here’s Officer Jason Dixon (Sam Rockwell), a violent, openly intolerant alcoholic who’s rumored to have tortured a black man in his custody. That’s a claim the other characters don’t deny so much as they defend on the basis of a lack of evidence. Dixon also gets declared a “good man,” if there’s any question of how little the term has to do with moral quality and how much it has to do with how many chances someone is given. Even Mildred herself is let off the hook for an assault she’s definitely committed. Dixon instead arrests Mildred’s black friend and coworker Denise (Amanda Warren) for possession, to use her as leverage (seemingly her only function in the movie). His colleague congratulates him for coming up with the idea.
Dixon’s behavior, and the way it’s tolerated by others, is depicted with a matter-of-factness that’s striking — but not nearly as striking as the disinterest the film has in actually engaging with that racism. It’s a disinterest that becomes clearer as Dixon becomes increasingly central to the last act of the movie, eventually starting to reckon with his anger and his brutality, but never with his bigotry.
I agree with everything Willmore says here. Three Billboards uses racist violence as window dressing, even as it tackles sexual violence head on. It made me feel deeply uncomfortable, and I don’t think in a way the film intended.
