The White House: Inside Story

The White House is one of America’s most iconic buildings; it is a symbol of shared national history and is home to the most powerful person on Earth. Here, the president charts the course for the country, and the First Family lives in the spotlight. It's a home, an office, and a museum. It's a bunker in times of war, a backdrop for command performances or state visits, and the heart of the American body politic.

Counterterror NYC

The NYPD's Counterterrorism Bureau is on the front lines in the war on terror. These specialized task forces have one goal: to keep New York City safe. During the busiest season of the year, Hercules teams deploy with 9-mm submachine guns, the TORCH team patrols New York's subway system and the bomb squad sweeps for explosive devices, all to secure the nation's largest city.
