Here's the bottom line of what people often times forget.
Balance is irrelevant. Just because on guy of one racial group goes to prison, doesn't mean that one of another racial group has to go to prison too for the sake of "balance". There is only 1 thing that matters, and that's the evidence. The facts. And while certain things like eye witness testimony should count for less in a court of law because it's unreliable, it's not to say that there's a problem with the system, but there's a problem with the actors in the system. Again, this is a sidenote to exemplify what I am talking about.
But I cannot stress this enough. Balance is irrelevant. I know this is absolutely mindblowing and bordering on heresy for people of a leftist mindset, but this is the correct mindset. You don't look to make "prison quotas" based on gender or race or any other collective determination. "Oh, we sent 1 black guy to prison, better send a white guy too for the sake of balance or else we'll seem racist!". That's how you get people doing abuse in the legal system. Just like affirmative action is abuse in the political and economic system. And I repeat myself, hoping against hope, that this notion hits home: BALANCE is IRRELEVANT.
