Imagine if some member of the bin Laden family was high on something and had rumors of their cousin's shenanigans and were spilling them out on some IRC channel or BBS or whatever, and that guy happened upon them and tried to alert the police, only to be dismissed as a lunatic and end up in prison for unrelated reasons while the disaster happened. That would be a true Kafkian nightmare.
That’s a very long shot but I now want someone to verify this claim too, in case he was also telling the truth.
