Suit make the man. Nightly news begins right now. Police were alerted to a serious Security Breach at a tsa screening checkpoint at jfk airport this morning. The only problem, they were alerted two hours after nearly a dozen passengers walked through what weve learned was an unattended metal detector. Nbc news has learned Surveillance Video shows some of those passengers actually triggered the alarms but continued into the terminal and onto airplanes unchallenged. The security gaffe raising questions about tsa staffing and whos in charge. Nbcs tom costello has details. Reporter it happened at 6 00 a. M. At jfk as the precheck lanes were opening. 11 passengers managed to walk through without being screened even though their carryon bags were. Three of the passengers tripped the metal detector, yet werent given a secondary screening. Two of the three shown here. But it took the tsa two hours to report the incident to Airport Police and by then the passengers were gone, already on their flights. In a statement the tsa says, a k9 team was present at the checkpoint at the time of the incident. We are confident this incident presents minimal risk to the Aviation Transportation system. Police say the passengers were identified and checked on arrival in california. At jfk today yeah, id say thats pretty unnerving. I dont know how that happens. Seems like theres pretty tight security here. I find it shocking given how tight security is these days. Reporter nationwide the tsa screens 2 Million People at 440 airports every day. So far, President Trump hasnt appointed a new tsa chief. Veteran deputies are running the agency, which has been under public scrutiny. Nearly two years ago, a devastating undercover test found agents failed to detect 90 of fake weapons and explosives. Meanwhile, from brussels to istanbul to ft. Lauderdale, airports remain a target. Security pros say todays lapse is a red flag. A checkpoint must be run properly, fully staffed. If you are unable to do that, it must be shut down. Reporter tsa says its investigating thoroughly. That could result in disciplinary action and retraining. But lester, more than 15 years after 9 11, day in and day out one of the Biggest Challenges the tsa faces is guarding against complacency.
