If you have a camera in the courtroom, there's no filtering. What you see is what's there.
The problem with not having a camera is that one must trust the analysis of a reporter who's telling you what occurred in the courtroom. You have to take into consideration the filtering effect of that person's own biases.
I know the pundits and the news media have carried a lot of commentary about cameras in the courtroom, and theres a lot of controversy about it as a result of the Simpson case. But I have not had enough time to step back and enough time to evaluate that.
