Are there any facts that indicate 9/11 was an inside job?

There are no facts about that. The fact is that Osama Bin Laden had been a very volatile terrorist extremist for years, very dangerous. He had already orchestrated the terrorist attack on the USS Cole on October 12, 2000, whick killed 17 sailors and wounded 39. He wasn't dealt with at that time and continued to plan his terrorist activity against the USA. Approximately a year later, September 11, 2001 he successfully orchestrated the terrorist attack against the Twin Towers. I don't think anyone ever thought that could happen on American soil, but it did, and changed the way we think of national security forever. Hopefully our diligence with security measrues will keep it from ever happening again.
