His name was John O’Neill, and I was tooling around on the internet yesterday when I came across him. He was the head of the FBI’s terrorism division that was following Bin Laden. He got so frustrated at the incompetence of the FBI and the Bush administration that he quit, and took a job as head of security at the World Trade Center. September 11, 2001 was his 2nd day on the job. He was killed. Here is an excellent Frontline on him. Of course conspiracy theorists have ha a field day with this.
