Occupy Wall Street protester Malcolm Harris (L) speaks with his lawyer, Martin Stolar, before a hearing in Manhattan Criminal Court stemming from his arrest in a protest march over the Brooklyn Bridge in New York, December 7, 2012. Prosecutors filed a subpoena on Twitter seeking months of Harris' tweets before and after the march, claiming they could undermine his defense that police appeared to lead protesters onto the bridge's roadway before arresting them for obstructing traffic.
