Lawyers for Moussaoui and the television networks asked U.S. District Judge Leonie Brinkema to overturn a ban on cameras in federal courtrooms, drawing sharp opposition from prosecutors in a case that will focus on the al-Qaida organization.
The Justice Department contended a worldwide broadcast ``might assist al-Qaida in retaliating against the witnesses who testify against it.''
Moussaoui, a French citizen, sat in his green prison jumpsuit, sometimes cocking his head to one side as he listened to the lawyers. He stands accused of six conspiracy counts of being an accomplice to the Sept. 11 attacks and could receive the death penalty if convicted.
Brinkema pointed to two small cameras to indicate that television would not physically disrupt the courtroom -- but also said she was concerned about the potential effect on participants. The cameras on Wednesday provided closed-circuit coverage to an overflow room for those who couldn't find seats.
Televised images of the trial, set to begin Sept. 30, ``are forever out there,'' she said. ``It does pose a security risk. If witnesses felt that photographs would be out there, that could be a chilling problem.''
The judge said she would rule Tuesday at the earliest.
Moussaoui's lawyer, Edward MacMahon Jr. spoke briefly and supported a televised trial with some restrictions. Television, he said, would provide Moussaoui with ``an added layer of protection'' for a fair trial. The defense does not want replays later in the day unless the jury is sequestered -- kept in a secure location under control of U.S. marshals.
TV and C-SPAN networks, contended the federal ban on cameras was unconstitutional and noted that Court TV already has televised more than 750 state and local trials.
The right to observe a trial should not be limited to a few dozen spectators crammed into a courtroom, Levine said. ``Television is ... a normal part of the courtroom procedure.''
