Most of the police that stepped over boundaries in this situation won't be prosecuted, and most of the extreme elements of the protesters—the people responsible for burning down buildings and looting department stores—won't be prosecuted either. That's not a symptom of corruption or racial prejudice or anything like that, but simply the fact that the situation in Ferguson is one of general chaos. There's no accountability in situations such as what Ferguson is evolving into, whether for police or protesters.
