The PIRA campaign that we are talking about started in 1969, a few years before "Bloody Sunday", so you can hardly say it "started the whole affair in motion" - actually I think the "whole affair" was started "in motion" hundreds of years ago... Anyway, this article is not about the British Army, it's about the PIRA, so we need to stick to their "contribution" to the death / injury count. And as I've said elsewhere, the PIRA have achieved very little else in the past 40 odd years, than kill and maim a lot of people. In ever repects (by their own published aims), they have failed. So although we do need to agree 
upon accurate figures, along with the sources to back them up - the information must appear in the lead for this article.
