Given that those responsible for the bombing are either dead, or even if found, would not be extradited to the UK to face a trail, it is a moot point if the relatives can ever get justice. But they do deserve the truth.
They have no chance of justice the IRA scum are now politicians. They will never apologise for their slaughter of working class people. How the left apologists in Britain can hold their heads up in the face of PIRA genocide has always been a mystery to me. Some on the left actually though PIRA were Socialist. Sigh!
