Apologies if I'm missing your point (it's not clear who you meant to reply to), but the article went through that analysis and determined that there's no income correlation, but an obvious correlation by racial makeup. That actually surprised me: I expected racially biased policing to be confirmed, but I also expected evidence of bias against poor people. (Though targeting them seems like a terrible way to increase revenue.) Edit: since they're analyzing cities relying on revenue from fines, this makes sense. You can fine poor people all you want, but if you end up jailing them when they stop even showing up to court, they're now a cost and not a source of revenue. Though there are businesses that somehow make money through fees on payment plans that only exist because they're for fines people can't afford to pay.
