Over at Reason's "Hit & Run" blog, David Weigel writes:

The guerrilla reporters of Infowars—last seen being broken up and hauled out of the spin room at CNN's Republican debate—nailed Michael Moore at a screening of Sicko and got him to discuss 9/11 conspiracy theories. (Sorry, other theories of the events of 9/11.) The reporters clearly ask whether Moore thinks "9/11 was an inside job," and he implies that... it might have been.

MOORE: Well, I've had a number of firefighters tell me over the years, and since Fahrenheit 9/11, that they heard these explosions, that they believe there is much more to the story then we've been told. I don't think the official investigations have told us the complete truth. They haven't even told us half the truth. And so I support, and I hope, you know, if there's a new administration or somebody could open up a new investigation of this before we get too far away from it, to find out the whole truth. Let me just give you one thing that has—I've asked for for a long time. I've filmed before, down at the Pentagon, before 9/11. There's got to be at least 100 video cameras ringing that building, in the trees, everywhere. They've got that plane coming in with 100 angles. How come we haven't seen the straight—I'm not talking about stop-action photos, I'm talking about the video. I want to see the video, I want to see 100 videos that exist of this. Why don't they want us to see that plane coming into the building? Because, you know, if you know anything about flying a plane, if you're going 500 mph, if you're off by that much, you're in the river. To hit a building that's only 5 stories high that expertly, I believe that there will be answers in that video tape and you should demand that that tape is released.

REPORTER: The idea that the hole is about 8 feet wide...

MOORE: See, I'm not very good at the physics and all that. But believe me, the questions need to be asked.

Update: Further thoughts from Allahpundit. Elsewhere, speaking of the left and cognitive dissonance...
