Heightened WTC Security Alert Had Just Been Lifted

The World Trade Center was destroyed just days after a heightened security alert was lifted at the landmark 110-story towers, security personnel said yesterday [September 11]. Daria Coard, 37, a guard at Tower One, said the security detail had been working 12-hour shifts for the past two weeks because of numerous phone threats. But on Thursday [September 6], bomb-sniffing dogs were abruptly removed. [NY NewsDay]
