I like this picture and coincidentally I was arguing with someone who insisted that the first plane that struck the towers may well have been "a small plane" because there had been numerous news reports that said so.
When I pointed out that there can be no doubt the second plane was a passenger jet, he agreed. I said, "what the Hell is the point of the first plane being faked and not the second?"
The answer: "Because it proves the official story's a lie!"
That's the weird world of Truthers!
Demonstrating once again that the Truthers are their own un-funny joke, being told over and over on a broken record. The picture is the famous webcomic xkcd, which regularly gets passed across the Internet, so I'm positive the picture is copyable.
Something you might want to ask this guy, angrysoba, is, "would an error in the 9/11 Commission Report count as a lie in your world?" I think the answer given his logic here would have to be yes.
