Zubaydah,Abu

From 9/11 Encyclopedia:

Abu Zoubeida aka Abu Zubaydah, was named on the FBI's list of most wanted bin Laden lieutenants (Beghal-C) before the CIA finally captured him at the end of March 2002 and started interrogatong him at an undisclosed location.

Many 9/11 Skeptics thought in 2002, that his whole personality is based on fabrications and doesn't exist or died a long while ago. "Zubaydah", while captured, confirmed that "the hijackers of Flight 93, the plane that crashed in Pennsylvania on September. 11, intended to slam the plane into the White House. http://www.guardian.co.uk/uslatest/story/0,1282,-1754798,00.html 

But in conflicting reports he "denied any knowledge of the attacks, telling his interrogators: "We don't kill innocent people...."

When Zubaydah was arrested in Summer 2002, a few Indian papers pointed as a "supporter of Bin laden", might be not the real Abu Zubaydah. South Asia Analysis Group (-> saag.org) came to the same conclusion: "...Pakistani intelligence officials, while not disputing the US identification, continue to say that they are not 100 per cent certain. 

According to them, the man identified by the US as Abu Zubaida also resembled Abu Hasham alias Abdul Latif alias Abu Amer Hashim, a Syrian..." http://www.saag.org/papers5/paper436.html

For bizarre reasons, Abu-Zubaydah (almost dead), later "warned" the FBI of an attack on the Brooklyn Bridge in NYC and confirmed a connection between Ramsi Binalshib (->) and some of the hijackers. At the time of this confirmation and the release of a new video including Binalshib, the NSA confirmed for the first time, that they translated another telephone call on September 11th, 
which revealed information about a possible 5th plane (->) and a crash into the White House.
