The long awaited report by Lord Saville into the killings on Bloody Sunday has been published.

In a nutshell, he has found what everyone already knew: The British Army shot unarmed civilians for no very good reason and then lied about it through a couple of inquiries.

Prime Minister Cameron has given a dignified response to Parliament and acknowledged what should have been said thirty years ago.

What David Cameron said:

What happened was "wrong".
Troops went in as a result of a order that should not have been given.
The first shot in the vicinity of the march was fired by the British Army.
None of those killed was armed.
There was some firing by republican paramilitaries, but none of this was justification for the reaction of the soldiers.
No warning was given by British soldiers.
It was a loss of self control by soldiers.
Some of those shot and injured were clearly fleeing or aiding other wounded.
One man was shot when was lying fatally wounded on ground.
None of the casualties were doing anything that could justify their killing.
You do not defend the British Army by defending the indefensible.
No point in trying to soften or equivocate what is in this report.
He said the tribunal found that some soldiers had "knowingly put forward false accounts".
Bloody Sunday was not the defining story of the army in Northern Ireland. He said the British Army, over the course of the Troubles, "had displayed enormous courage and professionalism in upholding democracy and the rule of law".
More than 1,000 members of the security forces lost their lives during the Troubles.
The prime minister also acknowledged the grief of the families: "Nothing can bring back those that were killed but I hope, as one relative has put it, the truth coming out can set people free."

The key lessons for me were always apparent: Don't deploy aggressive forces like paratroopers on a police mission (you don't train them to be passive and thoughtful) and if you murder civilians willy-nilly you guarantee recruitment for terrorists.

Now, enough is enough. I really hope they don't go down the route of trying to prosecute soldiers - the truth is enough and Ireland has long moved on.
