I won't argue against the justice system being systematically racist, I completely agree, and I'm also at work so I shouldn't engage in a big debate. I do, however, feel that some statistics, when compared white vs black, are somewhat skewed just because there is a much higher probability a black person is poor and won't be able to properly defend themselves compared to a white person. A poor white guy and a poor black guy with the same charge will likely get equally fucked by the law. I emphasised likely because I do know there are instances where this isn't true.
I'm not at all saying America is color blind, nor is the justice system, but I feel racism stems from class inequality, and bridging the gap between rich and poor is step 1 in ending racism.
