The Case of Malcolm MacArthur

The case of Malcolm MacArthur is so well known to everyone in Ireland isn't it? I wonder if you can give us the background for those not as familiar with it. O'Connell makes the point in his book that this was before the huge influx of heroin into Dublin which caused an increase in violent crime, gang of murders and so on. At that point notwithstanding the conflict north of the border, violent crime of that sort brutal random murder of a stranger was extremely rare,. It was a very very shocking case.
