The Department of Homeland Security unveiled its new National Terrorism Advisory System in New York City.
The U.S. Department of Homeland Security announced a new terror advisory system at Grand Central Station Wednesday. The system will no longer use color coded levels like orange and red, and instead will announce threats as either imminent or elevated. The elevated threat warns of a credible threat against the country, and imminent threat describes an impending threat against specific targets.
