Cameras in the Courtroom | Will SCOTUS and the US Legal System Join the 20th, if not 21st Century?

I'm a big believer in transparency, open platforms and letting people see what goes on to draw their own conclusions, but when it comes to legal system in the United States, it's still trying to catch up to the 20th century. One example of this is cameras in the courtroom.

 Retired Justice John Paul Stevens explains the pros/cons on the issue, but seems to acknowledge the cons haven't caused any problem in certain states or jurisdictions where they are allowed.
