Cargo: 'The Soft Underbelly'
The method of trying to ship the improvised explosives into the country on air cargo flights exposed one of the worst-kept secrets about American security.
At best, only a third of packages coming into the country as air cargo are ever inspected.
"I've called cargo the soft underbelly of aviation security because of the relative little security that is attached to it," said Clark Kent Ervin, former inspector general of the Department of Homeland Security. "I think this just underscores that fact that al Qaeda is always probing for weaknesses in the system and when we close one vulnerability, al Qaeda is just going to find another."
On Friday, Homeland Security agents and intelligence analysts were ordered to go back through previous shipments from Yemen over the last two weeks, as the White House worried that other package bombs might have already made their way into the country.
