An article by Paul Foot in '' Private Eye '' suggested that Jackson led one of the teams that bombed Dublin on 17 May 1974 , killing 26 people , including two infants . Royal Ulster Constabulary Special Patrol Group ( SPG ) officer John Weir ( who was also involved in loyalist killings ) , also maintained this in an affidavit . The information from Weir 's affidavit was published in 2003 in the '' Barron Report '' , the findings of an official investigation into the Dublin bombings commissioned by Irish Supreme Court Justice Henry Barron . Journalist Kevin Dowling in the '' Irish Independent '' alleged that Jackson had headed the gang that perpetrated the Miami Showband killings , which left three members of the cabaret band dead and two wounded . Journalist Joe Tiernan and the Pat Finucane Centre alleged this as well as Jackson 's involvement in the Dublin bombings . When questioned about the latter , Jackson denied involvement . Findings noted in a report by the Historical Enquiries Team ( HET ) ( released in December 2011 ) confirmed that Jackson was linked to the Miami Showband attack through his fingerprints , which had been found on the silencer specifically made for the Luger pistol used in the shootings
