Twitter has cooperated with NYC police in turning over data on a single user who made specific terrorist threats over the social network. The user announced his intent to shoot up the Longacre Theater tonight, which is the location of Mike Tyson’s one-man show. Twitter initially denied the request, pointing out that the same user had threatened “lots and lots of people” including several Kardashian sisters, Justin Bieber, and Chris Brown, none of which came to any harm. The company changed cource upon receiving a subpoena from the Manhattan district attorney. [Source AtlanticWire]
