“The majority of folks” who are found with firearms “are what we call low-risk passengers,” Jeffries said. “These are your more frequent travelers. They’re the ones usually in PreCheck. I don’t think there’s any malicious intent. The number one thing that we would hear out there, and I’m sure it still stands to this day, is, ‘I forgot it was in my bag.’”

This maybe more a reflection of how many people in the US own guns and less about people intending to stage some kind of shootout at the airport.
