TSA has always been totally polite. While they are sometimes a little disorganized, I've never seen them to be disrespectful. Personally, I think this story is totally manufactured.
Looks like we're going to get plenty more TSA-needs-to-be-dumped stories. Just wonder what Chertoff wants to replace them with? I'm sure if he had his way, we'd get Chinese Delta Force Commandos running our check points.
