Twitter refused to hand over the tweets of a Occupy Wall Street protester to New York authorities on Monday. The social media giant rejected a court order issued by the Manhattan district attorney, requiring it to release three months worth of tweets from protester Malcolm Harris, who was arrested along with 700 other activists last autumn. Harris made attempts to crush the subpoena in February. His motion was blocked by a judge on 20 April, who ruled that Twitter, rather than Harris owned the tweets.
