We may yet learn after all which News Corp executive instigated the telephone hacking by reporters and private detectives working for the London tabloid News of the World that touched off arguably the biggest journalism scandal in history. A British court ruled on Monday that private detective Glenn Mulcaire, one of two persons who were caught up in the original scandal and served time for their actions, must inform Nicola Phillips, who is suing News Corp, who hired him to hack the phones of politicians and celebrities. Mulcaire had invoked what in the U.S. would be called Fifth Amendment rights -- those that protect an individual against self-incrimination. Following the ruling, Mulcaire said that he would "comply with the Supreme Court ruling" but would assess "what the wider implications of this judgment are if and when I am asked to answer questions in other cases."
