The U.S. Department of Homeland Security announced this week that it will retire the current color coded threat alerts used at airports. The spectrum of green to red alerts has been in place since 2002, but in my own memory I can’t remember ever seeing a threat level below yellow (elevated). For most of the last 10 years it has remained elevated for long periods of time turning orange or even red. The new system aims to clarify specific threats to travelers with more information and should be in place by April. Let’s hope so. As DHS said, Americans need to be prepared, not scared.
