"And Loyalist in collusion with the British Government who ran a repressive, anti-Catholic regime for half a century where the direct cause of it happening." - Jim Carroll

As part of the Anglo-Irish Treaty of 1922, having been promised Home Rule in 1914 and again in 1920, Northern Ireland became a devolved self governing province of the United Kingdom. As such it had it's own Parliament but also elected and sent Members of Parliament to sit in the House of Commons, where, oddly enough, they were forbidden to bring up or debate any matters concerning Northern Ireland. That doesn't sit too well with Jim Carroll's ill-informed assertion that the British Government exercised any, let alone undue influence in how Stormont ran the internal affairs of Northern Ireland.

As to the percentages of those killed and by whom, they form a well worn path:

Killings by Military and Paramilitary Groups 1969-2001
Republicans: 2060 (58.6 percent)
Loyalists: 1016 (29.2 percent)
British Forces: 363 (10 percent)
Others – Unknown: 89 (2.2 percent)
Total: 3528
(CAIN – Sutton Index of Deaths. Appendix : Statistical Summary)

If those 363 killed by security forces were committed in the name of the British people. In whose name were the other 3,036 killed? The paramilitaries who carried out those killings certainly had no mandate at all from the people of Ireland (North or South).
