Court Cases in America

The George Zimmerman trial for the killing of Trayvon Martin is the latest case to receive public scrutiny thanks to every news station tracking and commenting on everything about the case. My problem with this "circus" America goes through every time a big court case occurs is that it's not innocent until proven guilty for these court cases and many times that's not what the media and public is looking for, they're looking for if the person is getting away with it or not. Now, personally I think Zimmerman did murder Martin and not in self defense, but it doesn't matter what I think, it matters what the jury decides happened in the event. I also don't need to see legal and psychological analysts on tv telling me what they think happened or is happening. Now I do believe that court cases should be public so that rights are not infringed upon, but I don't believe that the American people need everything about court cases analyzed by someone else. Personally, I feel court cases should have their own public broadcasting channel like C-SPAN that the cases can be shown without commentary so people can watch and make their own decisions as well as being watch dogs of the courts. Tell me what you think about it though, on the topic of the media and the United States court systems? (Please no comments on the George Zimmerman case, I just said I don't care about opinions one way or another on it, just gave it as the current example)
