The series of tests were conducted by Homeland Security Red Teams who pose as passengers, setting out to beat the system.
According to officials briefed on the results of a recent Homeland Security Inspector General’s report, TSA agents failed 67 out of 70 tests, with Red Team members repeatedly able to get potential weapons through checkpoints.
In one test an undercover agent was stopped after setting off an alarm at a magnetometer, but TSA screeners failed to detect a fake explosive device that was taped to his back during a follow-on pat down.
Officials would not divulge the exact time period of the testing other than to say it concluded recently
Homeland Security Secretary Jeh Johnson was apparently so frustrated by the findings he sought a detailed briefing on them last week at TSA headquarters in Arlington, Virginia, according to sources. U.S. officials insisted changes have already been made at airports to address vulnerabilities identified by the latest tests.
“Upon learning the initial findings of the Office of Inspector General’s report, Secretary Johnson immediately directed TSA to implement a series of actions, several of which are now in place, to address the issues raised in the report,” the DHS said in a written statement to ABC News.
