Read the whole thing. Here's another doozy: apparently you can bring any amount of liquid onto a plane, as long as it's in a bottle labeled "saline solution".
“The goal is to make sure that this ID triangle represents one person,” he explained. “Here’s how you get around it. Let’s assume you’re a terrorist and you believe your name is on the watch list.” It’s easy for a terrorist to check whether the government has cottoned on to his existence, Schneier said; he simply has to submit his name online to the new, privately run CLEAR program, which is meant to fast-pass approved travelers through security. If the terrorist is rejected, then he knows he’s on the watch list.
To slip through the only check against the no-fly list, the terrorist uses a stolen credit card to buy a ticket under a fake name. “Then you print a fake boarding pass with your real name on it and go to the airport. You give your real ID, and the fake boarding pass with your real name on it, to security. They’re checking the documents against each other. They’re not checking your name against the no-fly list—that was done on the airline’s computers. Once you’re through security, you rip up the fake boarding pass, and use the real boarding pass that has the name from the stolen credit card. Then you board the plane, because they’re not checking your name against your ID at boarding.”
