Oddly enough, I read about this in the RedEye first...

Kenneth Barrett was arrested for the murder of Catholic lawyer Pat Finucane, known for defending pIRA prisoners. The interesting question is whether the inquiry into Finucane's murder ends here. According to this and this, British intelligence forces might have had a role in this murder. If they did (and I don't know the facts of the case and won't pass a judgment on that one way or the other), they should face justice. I think the British over the last six years have done a good job owning up to their mistakes in the north of Ireland, and I hope that won't stop here.
