When expressed as a proportion of airport traffic volume, small airports in the West and South led the way. The airport in Roswell, N.M., had 8.5 guns intercepted per 100,000 passengers last year; Cedar City, Utah, and Provo, Utah, both 6.5; Longview, Texas, 4.9; Dickinson, N.D., 4; Joplin, Mo., 3.8; Twin Falls, Idaho, 3.4; Fort Smith, Ark., 3.3, and Walla Walla, Wash., and Elko, Nev., both 2.9.
By contrast, at John F. Kennedy International Airport in New York, where TSA screened nearly 27 million passengers last year, there was a single passenger found to have a gun.
"There are some Americans who believe that there are no limits, that they not only have a constitutional but a God-given right to have a gun and 'By gosh, if I want to bring a gun on a plane I'm going to do it,'" said Spitzer, a professor at the State University of New York-Cortland.
TSA's count of guns intercepted doesn't include all the other kinds of prohibited "guns" that TSA screeners find, like flare guns, BB guns, air guns, spear guns, pellet guns and starter pistols. Screeners find half a dozen to several dozen stun guns on passengers or in their carry-on bags each week. Last December, screeners stopped a passenger in Boston with seven stun guns in his bag. He said they were Christmas presents. The same week, screeners spotted 26 stun guns in the carry-on bag of a passenger at JFK. TSA has found several stun guns disguised as smartphones, and one that looked like a package of cigarettes.
Passengers are allowed to take guns with them when they fly, but only as checked baggage. They are required to fill out a form declaring the weapons and to carry them in a hard-sided bag with a lock.
