Well, as far as I know, Chuck Muth is neither a radical Muslim nor a former administration official with an ax to grind, if that's what you're worried about.
I woundn't count on this being disinformation. I have heard about the nutty airport screening procedures and the bureaucratic reluctance to arm pilots before.
I used to work in an airport for a government agency. This was right before 911. At the time, you could have taken over the airport with 6 well trained men.
Now it might take 7.
This what comes of career bureaucrats running huge departments. These are things we "ordinary" folks can see plain as day, but we are left completely out of the loop. If this continues, we're going to wake up one morning and see an entire US city vaporized. And if that happens, every one of these departments will be go into hyperdrive to cover their own butts and avoid blame.
