Oh, I followed the link to Dr. Bob's Blog alright and because it's on the internet it must be true, right? No names of Federal Air Marshals, just a nameless story.
Tell me something, if you were a Federal Air Marshal sworn to secrecy when an incident required such secrecy, would you blab such a story to your physician? I wouldn't. If he did, he should be fired because he is as much of a risk as the terrorists portrayed in Dr. Bob's story.
The point you're missing is I'm not criticizing Malkin's writing, especially in light of her saying she doesn't know if Dr. Bob's story is true or not. This Dr. Bob's story just sounds bizarre to me.
