Two throwing daggers were discovered in a passenger’s carry-on bag at Ronald Reagan Washington National Airport Monday, according to the TSA.



The weapons, each measuring just over a half-foot long, were found inside a hollowed-out book when the passenger went through a TSA checkpoint. The passenger voluntarily surrendered the knives and the hollow book in which they were kept.



The TSA has the authority to charge a civil penalty to passengers who bring dangerous and deadly weapons into the airport checkpoint.



The TSA recognizes that most passengers who bring these items into the checkpoint don’t do purposely with malicious intent. However, because common and seemingly innocent items like books can be used to hide dangerous weapons, it’s important that TSA officers are trained to look beyond the ordinary to ensure the safety and wellbeing of all employees and travelers.
