No revisiting the appalling vista
One of the legacies of the Troubles was an ambivalence towards violence. The sneaking regarder had looked the other way.
The tolerance was rooted in a conceit that somehow it was all "political".
But there is no room for murder in any democracy worthy of the name, there is no grey area which gives legitimacy to thugs beating someone to death, or putting a bullet in another human being's skull, because it's in the name of the "cause".
