A 9/11 Truther names Ryan Penn sent me an interesting note after hearing me on the radio this week:
I heard you on the radio a few weeks ago … You stated that a conspiracy/secret with too many people involved could never be keep a secret. Hmmmm … How many people were involved in the Manhattan Project? They were able to keep this a secret (estimates are as high as 60,000 people were involved in some way).
Thanks for the note, Ryan. I am familiar with the Manhattan-Project argument because it figures in Loose Change and various other 9/11 Truther movies. But it doesn’t support your point. That’s because of a key detail: The Manhattan Project was secret but legal. A plot to destroy the World Trade Center, on the other hand, would have been an illegal conspiracy to commit mass-murder. See the difference?
In the case of the Manhattan Project, it’s legal nature meant that it could be funded by legitimate government sources, housed in massive well-appointed, well-guarded facilities on government property, and staffed with (as you say) tens of thousands of individuals properly briefed in legitimate government security protocols. The fact that most or all of these people kept their mouths shut as ordered wasn’t because they were taking part of a secret scheme — but because they rightly regarded their efforts as part of a patriotic project to win World War II. If these people had instead been working on a criminal enterprise to slaughter America’s own citizens, you can bet that legions of them would have come forward once they’d understood the details of what they were being asked to do.
In any case, for the Manhattan-Project analogy to work with 9/11 Truth, the facts would have to be very different: The entire operation would have to have been kept secret, not only during WWII, but during the entire decade after, i.e. until 1955 (this decade-long period corresponding to the decade that has passed between 9/11 and 2011).
And obviously, that never happened.
