I expanded Vintagekit's version, which I felt had a better structure than the original, while reinserting some deleted material. I have also added some new information. Perhaps other editors might feel I have added too much on the background and reactions, but i felt that it was important in order to understand first the context of the killings and then their impact on public perceptions in NI. Vintagekits, do you still feel that there is superfluos info here?
