This comes hours after TSA announced that officers at Baltimore/Washington International Thurgood Marshall Airport caught a traveler with a loaded handgun at one of the checkpoints on October 9, bringing the total number caught so far this year to a record-setting 36 guns.

The previous record of 35 guns caught in a year was set in 2022.

‘It’s shocking to see that we have already surpassed the previous high number of guns caught and we are still in early October,’ said Grant Goodlett, TSA’s Deputy Federal Security Director for Maryland. 

‘Our TSA team here in Baltimore is good at what they do and they are remaining vigilant in helping to ensure that no illegal or prohibited items are carried onto a flight. 

‘There is absolutely no excuse for bringing a gun to our checkpoints because you certainly can’t carry it onto your flight.’
