After four years, the government finally released a few transcripts of hearings from Guantanamo that contained names of detainees. It wasn't a list. It was just a few transcripts where the names haven't been blacked out as they normally are. This is in response to a Freedom of Information claim by the Associated Press.

The Russians have a word for indefinite imprisonment for undefined political crimes by unspecified people.

Gulag.
