WASHINGTON — The Transportation Security Administration has a problem. More airline passengers are getting caught attempting to bring along a firearm in their carry-on baggage.

On Wednesday, the TSA released some alarming figures: In 2013, more than 1,800 firearms were detected at airport checkpoints across the country, up from more than 1,500 in 2012, 1,300 in 2011. Already in 2014, the TSA has found more than 900.

The TSA is so piqued by the number of people trying to bring their weapons through security – rather than legally declaring them at the ticket counters – that the agency held a brief news conference Wednesday to vent. And, to explain how one can buy hard weapons cases and declare a gun at the ticket counter.
