Speaking to to the BBC's "Sunday Sequence" the former Irish president said "We still probably don’t know the full truth, but it does appear that Osama Bin Laden was unarmed when the attack was made”.
She added “In those circumstances, it would have been appropriate that he would be arrested and brought to justice. That’s what happens to perpetrators even of egregious crimes.
“And I share an uncomfortable sense with the Archbishop of Canterbury. I would have preferred, if somebody is unarmed and can be captured and can be taken into custody, to be brought to justice. A great democracy would do that. It would have been appropriate that he would have been . . . brought to justice.”
She was referring to Archbishop of Canterbury Rowan Williams, who expressed his own concerns last week. He said "I think that the killing of an unarmed man is always going to leave a very uncomfortable feeling because it doesn’t look as if justice is seen to be done in those circumstances.”
