WASHINGTON, June 2 (UPI) -- An internal investigation by the Department of Homeland Security revealed Monday that undercover agents managed to get weapons through airport security in 67 out of 70 tests.
"The numbers in these reports never look good out of context, but they are a critical element in the continual evolution of our aviation security," Homeland Security Secretary Jeh C. Johnson said in a statement. "We take these findings very seriously in our continued effort to test, measure and enhance our capabilities and techniques as threats evolve."
