'See something, say something'

Homeland Security Secretary Janet Napolitano has unveiled a national "see something, say something" campaign in New York City.

Napolitano made the announcement Thursday in Penn Station, the nation's busiest train station. The campaign is part of an effort with Amtrak to increase information-sharing and engage riders in public security.

The slogan was inspired by the New York transit system's admonition to traditionally mind-your-own-business New Yorkers. It was instrumental in the foiled Times Square bomb plot when a street vendor did just that.

Napolitano also swore in John Pistole as administrator of the Transportation Security Administration. He is a former deputy FBI director who was confirmed by the Senate last week to fill the top TSA job.

On Tuesday Metro and other transit authorities staged anti-terrorism exercises to demonstrate their vigilance and to practice coordination of efforts with law enforcement agencies. In December, Metro created a 20-member anti-terrorism unit funded by a $9.6 million grant from the Department of Homeland Security.
