No surprise: they had Zacharias Mousouie (sp?) who was caught trying to learn how to fly but didn't care about how to land and the lawyers back in DC wouldn't let the agents look into his computer. Other field were worried about arabs taking flying lessons, their warnings were buried in DC. Probably many other incidents we have not heard about.
This is why no matter how bad the GOP may be, we can never ever vote for a RAT.
