Glenn Greenwald's partner detained at Heathrow airport for nine hours under Terrorism Act

``"This is a profound attack on press freedoms and the news gathering process," Greenwald said. "To detain my partner for a full nine hours while denying him a lawyer, and then seize large amounts of his possessions, is clearly intended to send a message of intimidation to those of us who have been reporting on the NSA and GCHQ. The actions of the UK pose a serious threat to journalists everywhere.''
