JFK is like a revolving door.
Via NY Daily News:
Eleven unidentified passengers walked through a security lane without being screened at Kennedy Airport early Monday because the TSA left the area open and unattended, law enforcement sources said.
A security camera captured a metal detector going off three times as the travelers walked through the screening lane, the sources said.
The breach happened around 6 a.m. at Terminal 5, but two hours passed before Transportation Security Administration officials notified the Port Authority Police Department, the sources said.
