The 9/11 attacks, or at least parts of those attacks, have been investigated by the 9/11 commission, the CIA, FBI, FAA, FEMA, The National Institute of Standards and Technology, the Senate Select Committee on Intelligence, the House Permanent Select Committee on Intelligence, Popular Mechanics, and countless mainstream newspapers -- among other sources.

None of these sources have concluded that there is any sort of grand conspiracy going on, that Bush was behind 9/11, that the Pentagon was hit with a truck bomb, that WTC 7 was brought down by a controlled demolition, etc.

So in other words, to believe in many of these kooky conspiracy theories, you have to believe that tens of thousands, maybe even hundreds of thousands of Republicans, Democrats, Independents, politicians, bureaucrats, journalists, FBI agents, and CIA agents all know about an incredibly complex, monstrous plot against the United States, and are keeping their lips sealed while Charlie Sheen, Rosie O'Donnell, and the fruit loops who think Bush is a puppet of the Freemasons have figured it all out.

For example, look at it like this: if you believe that a truck bomb hit the Pentagon and the government covered it up, you're in effect saying that you believe Bush, his cabinet, the FBI and/or CIA (who would have executed it), the eye witnesses, the rescue workers on the scene, people who work in the Pentagon, the newspapers that investigated it, Osama Bin Laden (who took credit for the attacks) and numerous other people all know that a truck bomb hit the Pentagon and are choosing to remain silent about it.

When I talk about looking at the big picture as opposed to conspiracy theorists focusing on tiny details, this is exactly what I'm talking about. Once you get out of the weeds where the crazies spend all their time looking at nearly irrelevant loose ends and start looking at everything that would have to fall into place to make this sort of X-Files scenario work, you can clearly see that it's impossible.

That's what people need to remember about 9/11: it has been investigated, in depth, by people from both parties, legitimate news organizations, and even Popular Mechanics, which is probably as close as you can possibly get to a non-political, non-partisan, unbiased organization in this instance and the conclusion is that there is no "there, there" to these conspiracies. That's why the only people who buy into them are the uninformed, the mentally unstable, and fools who don't understand that believing nothing that the government says is every bit as foolish as believing everything that the government says.
