Terror Threat, Really?

A credible but unconfirmed terror threat against New York and Washington, D.C., is ramping up already heightened security across the nation's capitol. Counterterrorism officials have warned against a possible car bomb attack as the 10th anniversary of 9/11 approaches. Homeland Security said they're investigating a detailed al-Qaida plot aimed at blowing up bridges or tunnels in New York or Washington. Unattended cars parked near critical infrastructure will be towed, officials in both cities said.
