Journalist criticises 'thuggish' anti-terror police

Guardian journalist Glenn Greenwald has told ITV News the goal of anti-terror police who detained his partner David Miranda for nine hours at Heathrow was "to be thuggish and [to] intimidate".

In his first British TV interview, Mr Greenwald claimed he has been targeted by the security services since he started reporting on alleged state spying but said he doesn't fear for his safety.
