“It is sad to see the U.S. justice system being politically corrupted right before our eyes like this.”
Actually, I think it is instructive. People are interested enough to pay attention to how the justice system works for a while, and it usually works pretty well, despite all the prejudice and anger in the community. You mentioned the Martin and Brown cases, which garnered much emotion, but in the end, the legal system followed the evidence, showed that evidence to the public, and was seen to have resolved those cases fairly, by most observers.
I expect the same thing to happen here.
I expect the same, which is why I said it would backfire on them and actually make matters worse.
The fact that there have been riots and people injured and killed as the result of the system finally working tells you that the system is, at the same time, being corrupted.
What these prosecutors, politicians and race baiters are doing is IMHO itself illegal and they should be held accountable for it under the law.
