Gothamist knows that some people are getting exasperated by the subway shootings ("Again?") but it doesn't mean it's any less disturbing. News that a man was shot in the face at a 7 train platform last night in Queens is crazy. But it might not be as random - the 23 year-old victim said, "I think I know him," after being shot, according to the police. Police are checking video cameras in nearby stores, as well as examining Metrocard records. Apparently they are hoping to find witnesses who fled the scene; Gothamist has always wondered about how Metrocards can be traced to individuals. One thing about the NYC subway system is that you only swipe your card when you get in - other subway systems, like London and Hong Kong, you swipe both when you enter and leave, leaving a clearer record of where you've been.
