It looks like the Transportation Security Administration will have found about 1,800 guns by the end of this year. So far in 2013, the TSA has discovered more than 1,500 guns at airports in the U.S. -- approximately the same amount found last year. "Our procedures have not changed," said Ross Feinstein, a TSA representative. "It's pretty well known that bringing a loaded weapon on a plane isn't allowed. Most people who travel understand."
