The only reason Im posting this is becouse Juan Cole seems to believe the documentary is credible. I havent seen it yet, but I trust him as a source. So, take it for what it's worth.

US Bin-Ladin Hunt Phoney

By Juan Cole
 November 17, 2008 "Juan Cole" -- - The USG Open Source Center translates an article from the Persian Afghan press alleging that French troops were at one point close to capturing Usamah Bin Ladin in Afghanistan, but that American forces stopped them from doing so. It says that a forthcoming French documentary containing interviews with the French soldiers provides proof for the allegation. The argument is that the Bush administration needed Bin Ladin to be at large in order to justify its military expansionism.
