A Coast Guard crew member patrols the Port of Newark in a 41-foot utility boat as a container ship unloads cargo at a terminal in Bayonne, N.J. The Marine Transportation Security Act, enacted on July 1, 2004, is designed to protect the nation's ports and waterways from a terrorist attack. The Coast Guard protects more than 361 ports and 95,000 miles of coastline, America's largest border. Homeland security--especially maritime law enforcement and border control--is the oldest of the Coast Guard's numerous responsibilities and dates back to its founding as the Revenue Cutter Service in 1790.
