When has this occurred? I use the Metro occasionally to go downtown to visit the museums, zoo, etc. Has there been any problems at Metro Center that you've heard or on any of the other lines?
L’Enfant is the site of the problems, with a couple more Greenline stations having occasional difficulty. We discussed this on FR a few weeks ago. http://www.nbcwashington.com/news/local/Teen-Mob-Attacks-Man-at-Suitland-Metro-Station-117102978.html http://www.myfoxdc.com/dpp/news/local/man-attacked-by-metro-mob-fights-back-012711 Etc.
