A teenager gets a year for acting as a lookout and the man who was responsible for killing him is deemed innocent until public pressure forces the convening of a grand jury. Even then, it seems, some believe he is the victim of an unfair justice system.

As an ousider looking in at what is happening in the USA it is obvious that your justice system is anything but fair. That the unfairness is clearly driven by racism is undoubtedly true. It depends on which side of the black/white divide you are as to which you believe gets the most unfair treatment.

I thought your constitution was meant to ensure that "all men (and women) are equal under the law" or words to that effect. It is looking not so much that a new civil war is about to break out but that the old one never properly ended.
