I'm conflicted.
On the one hand, it looks to me like the government definitely lied and tried to hide CIA involvement at first. And there is no doubt that the CIA wanted the UB on the plane and secretly helped him get on the plane by blocking the visa cancellation. The guy from the State Department admitted all that. From what I've read, the pax Haskell is also right about the government concealing evidence like the airport video so no one can see the UB's accomplice - aka CIA handler. And I'll concede that it is also true that in other cases (but not this case) there is proof that the FBI has been providing accomplices, cash and fake bombs to dumb & dumber terrorist patsies that they recruit. All this looks bad. Very bad. But like KSCessnaDriver and Gonzo say, it's not absolute proof. Qutch has presented a convincing case that lies are being told, the media isn't really digging into the story for some reason, and the government is hiding something here. But what? If the CIA were a regular person accused of a crime against flight 253, how could you convict them without absolute proof? Innocent until proven guilty? Is there enough evidence here to draw a conclusion?
