Notice, said maybe, if, stuff like that. I don't discount anything anymore after watching the clinton administration more or less skate on all sorts of issues including high level treason and arkanicide.
Personally, I believe some factions-some-in government did in fact know about this. Like, faa has reports of 4 planes hijacked, it takes 58 minutes to get fighter jets in the air. other reports going back years of warnings, and ignored lax airport security. Warnings about terrorists in conus ignored. etc. etc.
Makes ya go hm-m-m-m-m
I have no absolute proof of course, but then again, have no absolute proof of any other scandals of the past, from jfk whack on to today, but that one convinced me we have high level mercenary traitors in government, who can get away with assassinating a president, so I put nothing past them or their progeny. Even if this was a 100% pure unadulterated osama bin laden job, I still think it's looks suspicious and some of these bad guy traitor factions will take advantage of the fact, somehow.
My two rolls of reynolds wrap worth.
My guess is we will never find out who was short selling.
I think OBL had help from Saddam and other terrorist organizations.
