Yeah it's certainly more nuanced than just race. There has to be the right intersection of race, class, and social network to be above the law in the United States. But I'd essentially guarantee those white people being arrested all day are poor white people and generally not middle- or upper-class white people.
Exactly this. Obama's kid isn't being arrested when she drives through Martha's Vinyard in her Mercedes. Your chance of being arrested and spending time in prison is far more closely correlated with your income (or lack thereof) than your skin tone.
