Because humans are the ones interpreting the data, and the more experience one has doing so the better they get at it. New X-ray operators call for lots of bag checks, and use it as a learning opportunity, the more experienced an operator is the fewer bag checks they call for and the more likely they are to catch the prohibited item.
