America's Newest Anti-Terror Ally: Wal-Mart

A Department of Homeland Security campaign has moved from the subway to the suburbs.

The "If You See Something, Say Something" campaign - designed to get Americans to play a more active role in security - is coming to hundreds of Wal-Marts across the country.

"Homeland security starts with hometown security," said - Department of Homeland Security Secretary Janet Napolitano. "This partnership will help millions of shoppers across the nation identify and report indicators of terrorism, crime and other threats to law enforcement authorities."

The program was first used by the New York City's Metropolitan Transportation Authority and tries to get the general public to report indicators of terrorism and crime to authorities.

More than 230 Wal-Mart stores nationwide launched the "If You See Something, Say Something" campaign this week, with a total of 588 Wal-Mart stores in 27 states joining in the coming weeks. A short video message will play at some checkout locations with video monitors.

The campaign has already been implemented by the Mall of America in Minnesota, Amtrak, the American Hotel & Lodging Association and the Washington Metropolitan Area Transit Authority.
