The family of a lawyer killed in Belfast in 1989 said they ended a meeting with British Prime Minister David Cameron when he refused a full investigation.Geraldine Finucane told reporters outside No. 10 Downing St. she rejected Cameron\'s offer Tuesday to have a leading lawyer review of her husband\'s killing, The Guardian reported. She said she was almost speechless with anger.Pat Finucane was a Catholic solicitor in Northern Ireland who fought the British government in the 1980s in several human rights cases. He was gunned down as he ate dinner at home with his family, and his wife was wounded by the fusillade.The family said they will press for an independent investigation into whether security forces were involved in the killing. It was carried out by members of the paramilitary Ulster Defense Association, but some of those who took part are known to have been working for the Royal Ulster Constabulary or the British Army.Michael Finucane, Pat Finucane\'s son and a lawyer in Dublin, told the Irish Independent that Cameron offered only a \"paper review.\"\"We will not get to participate, we will not get to examine witnesses -- all we are being asked to do is accept the British government\'s word,\" he said. \"A paper review cannot make findings against individuals.\"
