It turned out that security video cameras that might have shown the man who walked through security at Newark Liberty International Airport were not recording during the incident. A Transportation Security Administration (TSA) spokeswoman said TSA-funded and Port Authority-installed and -operated cameras were running but not recording at the time of the security breach, which led officials to shut Terminal C for hours and rescreen thousands of passengers. She said TSA investigators instead scrutinized security tapes recorded by Continental Airlines’ cameras.

U.S. passenger rail operator Amtrak is reviewing intelligence related to the December 25 bombing attempt aboard a U.S.-bound jetliner and will increase security as necessary, the railroad said earlier this week. An internal advisory reminded Amtrak employees to be alert. “Although there is no specific threat to Amtrak identified at this time, we will be reviewing all intelligence gathered about the present situation to heighten awareness and to augment our security presence as required,” the advisory said. Unlike air travelers, Amtrak passengers do not undergo mandatory security screening before boarding trains. However, the government-run corporation that carries more than 27 million people annually on more than 300 trains per day conducts random passenger and bag checks.
