Fr Reid worked tirelessly for years to end the Troubles in Northern Ireland, today he died peacefully in hospital. He will be remembered.
Claims a shadowy military force were tasked with shooting IRA Volunteers - armed or not - are worrying, but not in the least surprising.
The PM said such a move would be 'rather dangerous' whilst none of the political parties in Northern Ireland supported the proposal.
Northern Ireland Secretary Theresa Villiers has expressed her "sadness" over Father Reid's death.
She said "We all owe a debt of gratitude to him for the role he played in the peace and reconciliation process in Northern Ireland."
Sinn Fein president Gerry Adams said he was "deeply saddened" by the death of Father Alec Reid.
He described Father Reid's base in west Belfast during the Troubles as "the cradle of the peace process".
Adams said: "I have not absorbed it yet. I knew him for the last 40 years. He was a very good friend of mine, of my wife, of my family."
He visited Father Reid in hospital in Dublin last night and was due to see him again today.
Paying tribute Adams added: "What Alec Reid did was he lived the gospel message. He developed a view which was contrary to the official view, that there had to be dialogue, and he was tenacious - I remember quite a few times saying he was like a terrier."
Father Alec Reid is best-remembered as the priest who gave the last rites to two British Army corporals who were killed after they drove into a republican funeral in 1988, says RTE.
In his effort to end The Troubles, he facilitated talks between Sinn Féin's Gerry Adams and SDLP leader John Hume.
He was trusted by senior figures in the IRA and also met several Irish Prime Ministers.
When the IRA eventually decommissioned their weapons in September 2005, he and Methodist minister Reverend Harold Good witnessed the arms being put beyond use.
In recent years he made several trips to Spain and worked to broker an end to the violent dispute in The Basque region.
A friend of former irish President Mary McAleese and her husband Martin, his funeral is expected to take place in Belfast on Wednesday.
Father Alec Reid, who was described as one of the architects of the Northern Ireland peace process, has died.
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."
Jude Whyte's mother was killed in a loyalist bombing in 1984 and he is a member of the Victims and Survivors' Forum. He welcomes the Northern Ireland Attorney General's call for an end to prosecutions relating to killings that took place during the Troubles.
He told ITV News: "I think he has made a very brave comment. He is expressing exactly what the parliamentary establishment and many victims' groups are saying.
"We have had 20 years of conferences, debates and groups and sub groups and we are no closer to an agreement. He's saying there needs to be a line in the sand and I agree with that."
He added: "I don't feel any prosecutions will bring closure - the truth will. In the case of the Bloody Sunday inquiry, it took 30 years to get the truth that people in Derry already knew.
"What is the logic for holding on to try and get a prosecution that is unlikely to happen. When do you make it stop?"
Former Northern Ireland secretary Peter Hain said he did not back a proposed amnesty for prosecutions in Troubles-related murders, but admitted efforts to punish crimes committed during the time was "difficult, if not impossible."
Speaking to Radio 4's World at One, he said:
"Pursuing crimes committed three or four decades ago at enormous expense, with enormous effort, where the evidence is very difficult if not impossible to achieve.
"It's better in my view, having dealt with these issues myself, to support the victims in their plea for justice in other ways.
"If you keep going down the legal route there's actually no prospect in the bulk of the cases that you are going to succeed and you just reopen the whole past instead of moving forward and instead of really addressing the victims' and the widows' grievances."
David Cameron has said the Government has no plans to legislate for an amnesty for crimes commited during the troubles in Northern Ireland.
Northern Ireland's Attorney General John Larkin earlier called for an end to prosecutions relating to killings that took place during the Troubles in the country.
Responding to a question by the DUP's Nigel Dodds, Mr Cameron said: "The Government has no plans to legislate for an amnesty for crimes that were commited during the troubles."
The Prime Minister added that the views of Northern Ireland Attorney General are "very much his own words" and do not reflect those of the Government.
