yeah, these three guys have been in detention for almost 5 years now and have been accused of being masterminds of the attack by USA.
in the interview, This guy lays out his motives clearly in the first 5 minutes. He wants to clear Muslim society of any blame for the attacks, and he was not directly involved in any capacity with this terrorist incident. He is just talking about what he heard after the incident, like any other guy who wants to prove his point. Intelligence is a very compartmentalized field, mainly based on the need-to-know basis, His previous work with INT does not provide any credibility to what he says.
