The criminal justice system is a mess, there's no doubt about that. If you want to see a stat that will blow your mind on rape "justice", check this out:

As far as this case goes, I'd say it's more a case of judicial incompetence than anything else. The judge's "logic" in imposing the sentence makes absolutely no sense from what little I've read about the case. I don't know anything about the judge, but if this is an example of his work, he doesn't belong on the bench.
Does this case say anything larger than that about the judicial system? I think it's undeniable that people with the means to hire good attorneys get off or get lighter sentences than those who are forced to use the lower end of the legal system. That sucks, but I don't know what to do about it. I don't buy cherry-picking and comparing cases and then saying this is a case of white privilege. It wouldn't be hard to find ample cases where white rapists are serving long terms. That said, I don't doubt that black people tend to get longer sentences than whites overall. I haven't seen any statistics on that, but I think that's the case. How much of that is due to skin color vs. differences in means to hire good attorneys is tough to say.
I hate the term "white privilege". I hate it, not because blacks don't have a demonstrable beef with the system, but because I think it's a case of looking at the issue bass-ackwards. In general, when a white person applies for a job, interacts with the judicial system, etc., there's a presumption that race isn't a factor (except for instances where affirmative action is in play). The person gets the job or is dealt with by the system simply based on the facts as to qualifications for the job or evidence as to guilt or innocence. That's the way the system is SUPPOSED to work for everybody. It's called civil rights. Calling it "white privilege" to me infers that it's some unwarranted right that shouldn't be permitted or that we should feel guilty about. What I think is that it's totally messed up that the system doesn't work that way for everyone, regardless of skin color. We've made tremendous strides since the days of the civil rights movement, but you'd have to either have you head in the sand or be a total hypocrite to deny that the system is not a level playing field.
