Hello and welcome to News Hour.
It's coming to you live from the BBC World Service studios in London.
I'm Tim Franks.
We're beginning with the most unusual court case.
unusual because it saw a man put on trial for a murder more than 50 years ago.
Unusual also
because it's become a symbol of a much wider debate over the balance between the search for truth and the search for justice from a long-running conflict.
That's a debate we'll look at in greater depth in a few minutes.
First, though, the specifics of this trial.
It took place in Northern Ireland, where for roughly 30 years,
up to the turn of the millennium, violence had flared.
Thousands died as rival paramilitaries launched attacks driven by sectarian division and nationalist ambition.
The British government had quickly sent in the army to try to restore order.
But what happened in 1972 and where today's trial came from was perhaps the single most infamous incident in the army's long,
contentious deployment.
It was called Bloody Sunday. 13 people were shot dead, 15 others injured,
when soldiers opened fire at a civil rights demonstration in a predominantly Catholic part of the city of Londonderry.
Back in 2010, at the conclusion of a belated and very extended inquiry into the killings,
the then British Prime Minister David Cameron called the shootings unjustified and unjustifiable.
