The 'inconsistancies' turn out not to be inconsistancies at all, once you take the time to learn facts and separate truths from the lies spread by the truth movement.
For example, I have inside knowledge about the OKC bombing, as one of my best friends served with, and knew well, Timothy McVeigh and others who worked with him. In fact, he was pulled from a field training exercise (from my side, in fact, where we were pulling OP (observation point) duty) by federal agents within 30 minutes of the bombing, for questioning.
So it was not an 'inside job' as in a planned government staged attack. It was a terrorist attack by an American dissident with more than a few mental problems, and his cult of easily mindwashed racist buddies.
Operation Northwoods was summarily rejected by the government, and its creator long considered a laughingstock among those in the know. Its continual resurfacing is no more or less suspicious than the continual circulation of the Protocals of the Elders of Zion, and both have about equal meaning to the underlying truths of 9/11 - namely, none.
There are thousands of rejected documents in the Government every year, from budget proposals to battle plans to personnel structuring. If we assume that every rejected document still represents a true and active plan within Government, we'd be accepting that all the government ever does is implement multiple, redundant, and often contradictory plans.
The mere existence of such documents proves nothing, any more than the mere existence of a book about the Red October proves that Russia had (and America has) a stealth sub.
Got anything else?
