Well, that's the $64,000 question, isn't it?
The "flag" they flew was that of Osama bin Laden and Al Qaeda. If we content ourselves with the mass media version of events -- as Raimondo appears to have done -- that pretty much ends the matter.
It was Al Qaeda and only Al Qaeda. How do we know? Because ABC, NBC, CBS, CNN, Justin Raimondo and our good friends in the gummint told us so.
I'm trying hard to believe that Al Qaeda acted alone. I really am. I don't want to be a thought criminal.
But, jeepers, the idea of Osama bin Laden and his gang of Keystone cutthroats pulling this off all by themselves is just so damn ridiculous. Maybe I'd better just head over to the Ministry of Truth and turn myself in.
