Attorneys for news organizations say there's no evidence that courtroom cameras would intimidate witnesses or violate defendant James Holmes' rights in the Colorado theater shootings trial.

In a court filing released Wednesday, the attorneys said objections raised by prosecutors and the defense to video and still photography are unfounded.

The media attorneys say cameras would give the public broader access to an important trial and improve understanding of the judicial system.

Holmes is scheduled to go on trial Dec. 8 on multiple charges of murder and attempted murder. He's accused of killing 12 people and injuring 70 in the 2012 attack. He pleaded not guilty by reason of insanity.

The Associated Press is among the news organizations asking to place one still camera and one video camera in the courtroom.
