Sounds like they arrested him just in time. That was good police work.
Airport personnel have always been one of the weakest points in security. A major airport has hundreds, perhaps thousands, of people with access to the planes. All it takes is one person to smuggle weapons or explosives on a plane. Airports across the US have been checking up on the ground personnel, often turning up dozens of people who aren't allowed by law to work around planes. It sounds like the French are cracking down, too. Good for them.
