I'm listening to Michelle Malkin on the radio and reading her blog on the difficulties the Federal Air Marshals are having with their boss Thomas Quinn. I agree the Marshals should be under cover. But that doesn't really go far enough. There aren't enough of them and we don't have enough money to protect a high proportion of our flights. As I have noted before there are better solutions, some with near zero cost, to in-flight security. And on the ground is this option if you want to spend money and effectively screen the passengers.
