Let’s hear it for private security firms

The good news: Security guards at Chicago O’Hare successfully confiscated two small folding knives found in a Nepalese student’s pocket. The bad news: Unfortunately, they failed to spot seven knives, a stun gun and a can of tear gas in his hand luggage as he carried them through the security checkpoint. He’d have carried them onto the plane if an airline employee hadn’t happened to search the guy’s bag at the gate.
