Politicians on all sides in Dublin and Belfast reacted in disbelief after the republican leader said that Chief Superintendent Harry Breen and Superintendent Bob Buchanan effectively drove themselves to their own death.
An eight year tribunal found an IRA mole in the Garda station in Dundalk tipped off a terrorist hit squad that the men were attending a meeting in the town on the day of the murders, March 20 1989.
Mr Adams claimed the RUC men thought they were immune from attack and had "a laissez-faire disregard for their own security".
In his 500-page report, Judge Peter Smithwick found there was collusion in the killings but he has not pointed the finger at any individual officer or civilian.
He found: "It is particularly regrettable that both police services acted swiftly to dismiss speculation of the possibility of collusion rather than to deal with that by means of a thorough and credible investigation.
"This was an example of the prioritisation of political expediency in the short term, without due regard to the rights of victims and the importance of placing justice at the centre of any policing system."
Members of an Army unit dubbed Britain's secret terror force have admitted breaking the law by firing on unarmed IRA suspects in west Belfast.
The Military Reaction Force (MRF) also carried out drive-by shootings of nationalists 40 years ago, even though there was no independent evidence any of them were members of the republican group, a new television documentary has claimed.
The elite soldiers believed military regulations prohibiting firing unless their lives were in immediate danger did not apply to them.
One told the BBC's Panorama programme: "We were not there to act like an Army unit, we were there to act like a terror group.
"We were there in a position to go after IRA and kill them when we found them."
A man has been arrested in connection with the IRA murders of two teenage British soldiers in Northern Ireland 36 years ago.
The 54-year-old suspect will be questioned about the gun attack on army vehicles in Belfast that killed 19-year-old Michael Harrison and 18-year-old Richard Turnbull, who were both privates from Yorkshire serving with the Light Infantry.
The ambush on North Howard Street in June 1977 left two other military personnel injured.
The arrested man was detained in west Belfast by officers from the Police Service of Northern Ireland's serious crime branch.
He has been taken to Antrim police station for questioning.
Crimestoppers are offering a reward of up £2,000 for information on the theft of the memorial plaque commemorating two boys killed by the IRA in Warrington.
12-year-old Tim Parry and three year old Jonathan Ball died in 1993 after the IRA detonated two bombs in the town centre on March 20, 1993.
The plaque is believed to have been stolen between April 20 and May 5 this year.
It is a sad reality that some individuals pay such little respect to the memory of those young boys whose lives were so tragically taken.
“It is disgraceful that something as sentimental as this plaque would be stolen for such small monetary gain when the illegal removal of it has such painful effects on the loved ones of the victims. It has stripped the family and friends of these boys from the peace the plaque represented and deeply upset the community in which it was taken from.

A bishop has condemned the theft of a memorial to two children killed by an IRA bomb.
This is senseless vandalism, grieving not only the families but the whole community. I appeal to all who have any information to assist the police and help take this investigation forward. My prayers are with the families as they cope with this appalling news.
– The Bishop of Warrington, the Rt Rev Richard Blackburn
