I tend to believe the entire thing is simply a ongoing distraction. Leading many "truthers" on a wild goose chase by simply keeping it tantalizing enough for them to continue to look.

For the vast majority they will accept the narrative while those who don't trust the government are left with just enough evidence to understand that the official story is incorrect but not enough to ever figure out that the entire thing was just an event to draw their attention away from something else that they won't ever have time to investigate. In the meantime the masses will be divided into those who don't believe and those who have no interest in not disbelieving. Divided once again while obscuring what may be really important.
