Not only is this another impressive demonstration of incompetence, but by disseminating the idea that people's luggage could be “secure” and “backdoored” at the same time, they're actually destroying what security has existed before. They should pivot to be the “Transport Endangerment Agency”.
Most luggage isn't really secure in the first place. It takes less time to open up a suitcase with a good knife than it does to unzip many suitcases. The idea that a little padlock will protect your suitcase from thieves is laughable. Like physical mail, the system is based on trust, and trying to patch security onto it is difficult.
