Bay detention camp. Schwartz was allowed to sit in a separate room behind three panes of soundproof glass and watch the tribunal in real time, but a 40-second delayed audio feed inside the room ensured that no classified information was inadvertently leaked.

But Schwartz noticed a problem. What Schwartz saw from behind the glass didn't jibe with what he heard over the audio. That's why the reporter is now suing the Department of Defense and several other agencies to get some answers.

The lawsuit is the latest attempt to chip away at the deep secrecy that shrouds the detention camp, which was established 14 years ago to house suspected terrorists and which President Barack Obama has been fruitlessly trying to close for the past seven years.

The way Schwartz describes it, as he sat in the room watching the proceedings, a red light would begin flashing as a warning that the feed would be cut when sensitive information approached. The feed would then resume after the classified info was uttered.
