This is not about a cause or Trayvon or Zimmerman. It is about thugs who are looking for a reason to behave the way they want to. Of course they aren't rallying or demonstrating. That isn't what they find interesting/fun/profitable at the moment. After the verdict, it will be like the urban 4th of July. Although, I am sure they will be excused by the media and our President for blowing off a little steam.
