This is an article from The Atlantic in 2006 but I thought it a great read on the History of the IRA from the British perspective.-SF

I first met the man now called Kevin Fulton in London, on Platform 13 at Victoria Station. We almost missed each other in the crowd; he didn’t look at all like a terrorist.
He pressed a thick index finger against Fulton’s temple, hard, then leaned in close to Fulton’s ear and murmured a series of threats: The IRA hunts down all snitches and executes them. Two quick bullets in the brain. Remember the boy from County Armagh who left behind the pregnant wife. Remember the boy from County Louth who left seven children mewling for a father. Remember them all.
