I can see demonstrations, I think the reality of the matter will prevent any large scale rioting. Anyone who's paying attention to the trial knows that the prosecution has not proved anything beyond reasonable doubt. If it was clear that this was 100% not self-defense I could see a stronger reaction, but I think it's obvious Zimmerman shot Trayvon in the heat of a physical altercation, one in which Zimmerman was injured. That right there makes a guilty verdict pretty much impossible based on the state seeking 2nd degree murder.
True but you are expecting people to act with their heads. I don't, I think it will be all emotion and it will feed upon itself and lead to rioting.
