This Bloody Sunday thing is a bad business.

Don't get me wrong, anyone who has looked even superficially at the details of the Saville Report will tell you that crimes were undoubtedly committed by British troops on Bloody Sunday. The commanders on the ground that day lost control of their troops and people were illegally killed. Those things should have been dealt with long before now.

However, for a man in his 70s to be facing prosecution for something that happened nearly half a century ago while terrorists who committed much worse crimes enjoy immunity goes against all notions of natural justice and is rightly abhorrent.
