Words not to use on social media, according to DHS
Do you tweet about WMATA on a regular basis? Have you ever posted to Facebook a lament about a power outage? Or perhaps you've updated your friends and followers about how your airplane trip to Mexico was canceled?
We ask because, according to the results of a Freedom of Information Act request by the Electronic Privacy Information Center, all of those words are considered "red flags" by the Department of Homeland Security.
While the list includes some obvious choices that could raise alarm bells - dirty bomb, Al-Qaida, nerve agent and jihad are among them - some seemingly mundane words are included as well.
Some of those include "Metro" and "WMATA," as well as several normal weather terms like storm, hurricane, ice and snow.
