Poor people in poor neighborhoods commit more crimes. This is true. More black people live in poor neighborhoods than white people. Also true.
So even without racism there will be more black people, per capita, than white people getting charged with crimes. But to bury your head in the sand and think that either a) the law is applied fairly and evenly or that b) it isn't bad for society if black people get scrutinized more aggressively by law enforcement well, you're wrong. Well, you're wrong unless your version of justice means that racial divides need to be maintained and that the freedom of black people is less important than the freedom of white people or that they need to be held to a higher standard to keep from being locked in a cell, or that the innocent law abiding friends and family of unjustly prosecuted black people should just keep on being innocent law abiding, tax paying, productive members of society despite the pain and loss they suffer from having their friends and family unjustly incarcerated.
You all know I'm all about freedom and individual liberty. Makes me sad how often people claiming the same focus on how much they have to pay in taxes or how their kids are being brainwashed into being homosexuals. There can be no individual liberty in the face of such overwhelming injustice. It just doesn't work. Our out of control prison system, our unjust selective enforcement of the law and the way both of those things are tied to a person's ability to earn a living is a horrible injustice. Easy to ignore if you are not affected by it, impossible to ignore if you are.
I think we need to look at this one from a macro perspective. "Sending in the troops" to targeted areas does more than just imprisoning minorities. Creating a sense of rule of law helps children feel safe, which helps them build constructive goals and focus on the things that should matter.
The problem isn't racial enforcement IMO, it's an unwillingness to take the next step and provide an infrastructure in which children from these areas can thrive in. But then, those who've studied this the most don't really have any answers to this issue so why should I.
