The Obama Administration reversed course this morning, admitting the nation's security system failed when a man apparently tried to blow up a Northwest flight over Detroit Christmas day.
Janet Napolitano, Secretary of Homeland Security, says "our system did not work in this instance. No one is happy or satisfied with that. An extensive review is underway."
Janet Napolitano says she was talking about alerting other airlines, not catching would-be bombers, when she said earlier the system worked.
Today, as the government goes to court seeking a DNA sample from suspect Umar Abdulmutallab, Washington's put new restrictions on holiday travelers.
And is conducting a full review of how the 23-year-old Nigerian got explosives through security onto Northwest Flight 253 from Amsterdam to Detroit on Christmas day.
Roger Cressey, Security Analyst, says "he put his explosive package, if you will, next to his "package" which guaranteed that it wouldn't have been screened the way that traditional things are being screened right now. That's a vulnerability we've got to fix."
Abdulmutallab, who was taken down by passengers, was on a government terrorism list after his own father reported suspicious behavior.
But that didn't prevent him from flying.
Michael Goldfarb, former FAA Chief of Staff, says "Wal-mart has a better tracking system than the U.S. Department of Homeland Security."
Analysts say the government's got to do more, that restricting carry-ons and making passengers sit for the last hour of the flight are not enough.
One of the things the government will be looking at is expanding those security machines that puff air on passengers to detect explosives.
Magnetometers don't detect explosives.
