Private investigator Glenn Mulcaire leaves after the sentencing at the Old Bailey court house in London July 4, 2014. British Prime Minister David Cameron's former media chief Andy Coulson was jailed for 18 months on Friday for being complicit in industrial scale phone-hacking by journalists at the Rupert Murdoch tabloid he edited. Mulcaire, the former private investigator who conducted much of the hacking, was given a six month suspended sentence. REUTERS/Luke MacGregor (BRITAIN - Tags: MEDIA CRIME LAW)
