Puppet Masters
That is despite the British government's security adviser deciding MI5 had no connection to the Derry death of Kieran Doherty (31). No inappropriate or improper action took place, Lord Carlile added.
Mr Doherty's body was discovered on the outskirts of the city close to the Border in February 2010. He had been shot dead. The Real IRA said he had been killed because of links to the drugs trade.
Mr Doherty's uncle Vincent Coyle said: "There is a case now for the Police Service of Northern Ireland (PSNI) to carry out an investigation into this."
He added: "The security services seem to be left doing their own thing. The old Royal Ulster Constabulary Special Branch took huge pay offs on the Monday and were back as MI5 officers on the Tuesday."
Lord Carlile spent four months investigating the family's claims MI5 were involved in the killing and met relatives. He sent a letter to SDLP Foyle MP Mark Durkan.
The device exploded under the vehicle outside his home in Highfield Close, off the Gortin Road in Omagh, Co Tyrone, just before 4pm today.
It is understood the 25-year-old was a new recruit to the Police Service of Northern Ireland and was a Catholic.
Shadow Northern Ireland secretary Shaun Woodward said: "This evil and cowardly attack will sicken everyone across Northern Ireland.

A forensics team examines the scene where significant arms were found in Coalisland, east Tyrone, during the investigation into the murder of Ronan Kerr.
Dissident republicans who prepared a 500lb (227kg) van bomb risked causing an Omagh-style massacre, politicians in Northern Ireland have said.
Detectives believe the bomb, found at an underpass near the border on the main Belfast to Dublin road, may have been destined for a town centre attack.
29 people were killed and 220 were injured in a bomb attack in the centre of Omagh in August 1998.
While it is believed the presence of a police checkpoint forced the latest bombers to abandon the vehicle, hundreds of motorists drove past the device unaware of the danger after traffic cones and warning signs had been removed, and even driven over, by others on the road.
The blue Ford transit van, stolen in Maynooth outside Dublin in January and carrying false Donegal registration plates, was found near Newry and contained a wheelie bin packed with 500lbs of homemade explosives.
The main goal for the IAEA (International Atomic Energy Agency) is to propagate atomic energy. This is stated clearly in paragraph 2 of the IAEA statute:
"The Agency shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world."Moreover, many UN agencies are subordinate to the IAEA. This particularly applies to the World Health Organization (WHO). On the strength of an agreement signed on 28 May 1959 (WHA 12-40), the IAEA can veto any research carried by WHO which would be in opposition to implementation of paragraph 2 of the IAEA statute. One statement in this agreement reads:
"It is recognized by the World Health Organization that the International Atomic Energy Agency has the primary responsibility for encouraging, assisting and coordinating research on, and development and practical application of, atomic energy for peaceful uses throughout the world without prejudice to the right of the World Health Organization to concern itself with promoting, developing, assisting, and coordinating international health work, including research, in all its aspects."So it's easy to assess the relative value of reports about the effects of nuclear disasters published by the pro-nuclear institutions, including the famous 2005 report on Chernobyl (a favorite reference for pro-atomic lobbyists). In short, in the interest of "encouraging, assisting and coordinating research on, and development and practical application of, atomic energy" such reports are very probably biased and tend to downplay the extent of the radiation danger to people.

A Yemeni anti-government protester takes part in a demonstration in the commercial capital Taiz.
Speaking at a rally of his supporters, Saleh lashed out at the Gulf states who have been meeting in Riyadh, Saudi Arabia, to discuss his fate. He accused them of trying to mastermind a "coup" against his country's democracy and of "blatant interference in Yemeni affairs".
Violent demonstrations continued, with three protesters killed in the city of Taiz, the commercial capital. Protesters carrying the bodies of five people killed earlier in the week to a graveyard came under fire from soldiers from the Republican Guard, an elite force headed by the president's son.
Plain-clothed men were seen crouching on nearby rooftops firing rifles and lobbing tear-gas canisters down on the protesters.

John Boehner, left, and Barack Obama each announced a shutdown had been avoided.
The deal - which was only sealed after Boehner presented the outline to a closed door Republican Conference - averts what would have been an unprecedented wartime shutdown of the government that had become a growing embarrassment for himself and President Barack Obama.
Down to the end, Boehner was still pressing for a lower top line when Obama called him in the early evening. Both men later cast the agreement as the best available, but the grueling, often distrustful process testified to how tough this legislative year will be and the immense pressure on the speaker from the right.
The administration largely succeeded in blocking the most controversial policy riders impacting the environment and abortion-rights. But the cut is one of the single largest in history, and a preview of what lies ahead when Republicans move their 2012 budget plan next week and fight with Obama over raising the debt ceiling in May and June.
"Like any worthwhile compromise, both sides had to make tough decisions and give ground on issues that were important to them," Obama said. "And I certainly did that."
It would depend, he said, on what the Iraqis want and what Washington is willing to give.
Gates met soldiers of the 4th Advise and Assist Brigade, 1st Cavalry Division, in Mosul, where - like the troops Gates met one day earlier in Baghdad - they asked if they would actually be staying beyond 2011, and if so, for how long.
"Well, I think that would be part of any negotiation," Gates answered, "... whether it would be for a finite period of time, whether it would be negotiated that there be a further ramp down over a period of two or three years, or whether we would have a continuing advise-and-assist role that we have in a number of countries that just becomes part of a regular military-to-military relationship."
Any extension, however, would be smaller than the current 47,000-member force in Iraq.
During his travels, Gates nearly always meets small groups of deployed troops. Each time, he gives a short speech and answers questions on topics ranging from global policy decisions to getting washing machines and Internet connections fixed. The secretary shakes each hand, takes a picture and hands out hundreds of his personalized commemorative "challenge" coins - a military tradition.
The strikes came hours after mortar rounds and a rocket were fired at the residence of the French ambassador in Abidjan by pro-Gbagbo forces.
A spokesman for Mr Gbagbo denied that the French ambassador's residence had been attacked.
"The Ivory Coast government believes France is looking for a pretext to resume bombings on the presidential palace," Toussaint Alain, a representative for Mr Gbagbo, said in Paris. "If there are attacks on the embassy, it's not Gbagbo's forces. Nobody has been attacked."
The UN peacekeeping head said Mr Gbagbo's forces had regained ground in Abidjan and fully control the Plateau and Cocody areas.
Alain Le Roy said the Gbagbo camp had used a lull on Tuesday for peace talks as a "trick" to reinforce their positions and that they still had heavy weapons.
The minister were meeting in Budapest on Friday to discuss the sovereign debt crisis that has haunted the bloc for over a year, with Portugal the main focus of their talks.
Debt-laden Portugal on Thursday became the third eurozone nation after Greece and Ireland to request financial help from the European Union and the International Monetary Fund after a spike in borrowing costs.
Jean-Claude Juncker, the head of the Eurogroup, said the finance ministers had instructed the EU, the IMF and Portugal's politicians to negotiate the country's bailout by mid-May for implementation after June 5 elections.
"The package must be really strict because otherwise it does not make any sense to guarantee anybody's loan," Finland's Finance Minister Hyrki Katainen said.
