The fact that a small ~1000 person poll done by telephone shows who people "trust" says nothing at all about the original video discussed in this thread. From what I can tell, *you* brought up the subject of the video being faked, not bill. Stay on topic.
Re: wikipedia. True, that anyone can post anything, but incorrect facts WILL find themselves being corrected. I just did a brief scan of the WP article bill linked to, and I can find no bias. (Please show it to me if it exists.) I also see 280 citations from external sources, which would seem to indicate that it is not all "made up." Of course I don't have the time to verify each of those, and I'm sure you don't either, but I'm sure given the number of eyes WP sees, they've checked out.
If you're really interested, pencil in a few hours and try this:

I caught the 2-hour "abridged" version that was on a while back. Wasn't aware this was a four-hour piece until I looked it up.
