Prosecutors asked a judge to dismiss a request by the lawyers for the Tucson shooting rampage suspect to have all psychiatric assessments of their client videotaped while he's at a prison medical facility in Missouri.

The prosecutors say in a filing late Tuesday that the request by Jared Lee Loughner's attorneys doesn't cite any relevant legal authority and is impractical because it could be interpreted to seek non-stop videotaping of their client.

Defense attorneys say the videos would likely have evidentiary value.

Loughner has been at the facility in Springfield, Mo., since May 27 after he was declared mentally unfit to assist in his legal defense.

He has pleaded not guilty to 49 charges in the Jan. 8 rampage that killed six and wounded 13, including U.S. Rep. Gabrielle Giffords.
