A few questions:
Was the decision not to indict unjust?
Did the evidence warrant an indictment or possible conviction?
If the evidence was not corroborative to an indictment, then do we need to change the laws? Why?
These are important questions, because if their answers aren't basically yes, no, and if need be, yes, then anyone protesting or angered at the outcome of the Wilson grand jury is standing on loose footing.
There is not a question that something needs to be done about the adversarial relationship between law enforcement and urban citizens, but if the evidence and decision not to indict agree with the law, and the law is sound as is, then Michael Brown is a poor choice for a martyr, and any demonstrations or social unrest with him at the center is weak.
