Colleen Chien, a law professor at UC Berkeley, has been publishing legal data across California related to RJA and studying legal disparities. “What we’re seeing is that there’s what we already know, there’s a lot of racial disparity in our system, and it’s really pervasive — almost every single county, on every single charge,” she said. “It’s hard to believe that that could just be the product of things that don’t have to do with racism.”
