(The Hill) — Homeland Security Secretary Janet Napolitano on Wednesday stressed the importance of solidifying a partnership between government intelligence agencies and private-sector business in the U.S.’s struggle to thwart terrorist attacks.

Less than a month before the 10th anniversary of the 9/11 attacks, Napolitano addressed a full room of business owners at the U.S. Chamber of Commerce as part of the Department of Homeland Security’s expanding “See Something, Say Something” awareness campaign, which relies heavily on information-sharing from private citizens and local businesses.

“My hope and my charge to you today is to help us spread this public awareness message,” Napolitano said. “Quite frankly, we need all hands on deck in this effort.”

Napolitano announced a series of new public service announcements Wednesday that advertise the public-awareness campaign of identifying and telling authorities about suspicious activity. She encouraged the business owners in the audience to share the 30-second video spots with their colleagues, link to them on their company websites and include them in their own marketing campaigns.

“You know, as members of the private sector — and I know, in my role as secretary — how hard it is to get a message across to the general public and get them thinking in that way, right?” she said. “No government department, no matter how large or how well-run, can do it by itself, and the private sector, no matter how large and well-run, [can’t] do it by itself [either]. It has to be a partnership, and the public has to be involved.”
