In 1998, Tony Blair announced a new judicial inquiry, the Bloody Sunday Inquiry, into the killing of 13 unarmed civil rights marchers in Derry in 1972. A previous investigation, the Widgery Tribunal, into the same event had been discredited. During the debate in the House of Commons, Trimble was one of few dissenting voices. He said "I am sorry to have to say to the Prime Minister that I think that the hope expressed by the Honourable Member for Foyle Hume that this will be part of the healing process is likely to be misplaced. Opening old wounds like this is likely to do more harm than good. The basic facts of the situation are known and not open to dispute." Reporting in 2010, the Saville Inquiry confirmed that all of the 13 killings and 13 woundings were unjustified.
