Do you seriously think the FBI or whoever would release frames of a video that so clearly undermine the "official" story of 9/11? That there is a vast conspiracy competant enough to pull of a massive terrorist atrocity which leaves few conclusive idicators that it was a plot from within, and yet stupid enough to then release a gem of evidence like that to the public on a whim?

You're getting high
On the downlow
A victim of the COINTELPRO
You're wrong
And you'll probably never know

Edit: With regards to the Loose Change documentary that people are starting to talk about, it's probably worth reading this first.
