I was told the when 9/11 happened, he wasn’t in the inside group who knew about the governments planned attack on the twin towers. When it happened it took him by surprise. After he helped the city for the next couple days after the attack, he put it all together &eventually learned that it was an attack by our own government. He couldn’t say anything because of the horrible threats against him and others. It could all be bullshit, but I thought I remembered that being the case.
