That statistic has since risen to 73 percent following the discovery of another illegally carried firearm Wednesday.
“While no one should try to bring a gun through airport security, an increase from 30 guns in luggage at RDU last year to 37 so far this year, out of about 10 million travelers, is not exactly an epidemic,” said Jeffrey Welty, associate professor in the UNC School of Government and expert on firearm regulation, in an email.
As of Wednesday, the amount of firearms found rose to 38.
These incidents often happen by accident because passengers are unaware of the items in their carry-on luggage, said Beth Walker, the federal security director of the RDU airport TSA.
“When we do discover a firearm at the checkpoint, that about 98 percent of those passengers say they forgot that it was in their carry-on,” she said.
The consequences for passengers range from an encounter with law enforcement to arrest or even a civil penalty of up to $11,000 per incident, she said.
“None of those guns seem to have been misused, and TSA itself has stated that most incidents involve inadvertent oversights rather than intentional efforts to circumvent federal law,” Welty said.
The increase in firearm presence in carry-on bags is nationwide, Walker said.
