If you can't keep your mouth shut about classified information, you shouldn't be an Air Marshal or have any other job that requires working with classified material.
Even if the information seems harmless, it's not up to those individuals to determine what material they think is safe to leak and what isn't.
Our government leaks like a sieve, and we need to start aggressively plugging those leaks.
This leaker appears to be a current or former Air Marshal but just being a part of a program doesn't make him an expert on the underlying ops.
It seems he/she gave CNN some opinion about how he thought things should be and threw in some numbers without substantiating facts backing them up.
Just talking to the MSM about Government Ops without authorization is a violation of the law in itself and I hope he/she goes down.
He/She wants to claim Freedom of Speech but he/she didn't just stop at informing congress about their perception but they put it in bulk e-mail.
