A review of one of the most notorious killings during Northern Ireland's Troubles, has confirmed that â€” in the words of Prime Minister David Cameron â€” there was a "shocking" level of collusion by agents of the state. Cameron made an extended statement in Parliament on Wednesday. Belfast Lawyer Pat Finucane was shot dead by Protestant loyalists in front of his family in 1989. Sir Desmond de Silva's report confirms what's been open knowledge in Northern Ireland for years â€” that members of the Royal Ulster Constabulary, Northern Ireland's British-backed police force, were involved in the killing and then obstructed the murder investigation. It was also revealed, for the first time, that Britain's MI-5 had spread disinformation about Finucane before the killing.
