I wonder if Sir Michael Jackson permitted himself a wry smile about atrocities as he retired last month as Chief of the General Staff.
Stepping down after three years, Jackson's mind may have drifted back to the Bogside and Bloody Sunday - the day he began the rise through the ranks that was to take him to the top.
The exposure of Jackson as the man who masterminded the cover-up of the Derry massacre has never hit the headlines. It appears to have gone unmentioned in any of the biographical pieces which marked his retirement. But it may figure prominently in the long-delayed report of the Bloody Sunday inquiry under Lord Saville. If it doesn't, people in Derry will draw certain conclusions about Saville.
