Just look at our airports today. Security has become paramount, yet we're alarmed by media reports of travelers who have been able to circumvent security and carry potential weapons past checkpoints. How is this possible during a time when our airports are on such a state of alert? Are the metal detectors failing? No. The problem isn't the machines. The problem is the human factor: The people manning the machines. Airport officials can marshal the National Guard and install metal detectors and facial recognition systems, but educating the frontline security staff on how to properly screen passengers is much more likely to help.
