There have been many injustices when looking at convictions and sentencing. No one is saying racism doesn't exist in the justice system. But there is no hard evidence this is the case here. You can't just say well he only got two years prison, the justice system must be racist, and because Kansas. Quite a few mitigating factors. I've seen plenty of 'misjustices' where there was no difference in race between the victim and perp.
If anything socio-economic status seems to be the larger factor then race. If you're rich, you can **** a 3 year old and get no jail time. You can run over people drunk and kill and get rehab.
