That's true, but all FISA proceedings are classified, so there's no way they would allow cameras.

Well, they might allow cameras -- "classified" does not mean "no records" -- but any photos or video would also be classified.

They certainly wouldn't allow the media (or the public) in the courtroom, with or without cameras, or allow the media/public access to anything any cameras they did allow in captured.

Yes, but the rule is a part of general federal court procedure rules.
