The Partnership for Public Service honored the nine winners of this year’s Samuel J. Heyman Service to America Medals at a Washington, D.C. gala Thursday evening.

This video features Nael Samha and Thomas Roland, Jr. of U.S. Customs and Border Protection, winners of the Homeland Security medal. Samha and Roland created a smartphone application that allows customs and border agents in the field to access law enforcement databases in real time, which has led to enforcement actions against more than 450 drug traffickers, weapons smugglers, illegal aliens and potential terror suspects since March 2010.

The medals, popularly known as “Sammies,” are awarded to public servants who are making high-impact contributions to the health, safety and well-being of Americans.
