The Pat Finucane Centre has named the Miami Showband killings as one of the 87 violent attacks perpetrated by the Glenanne gang against the Irish nationalist community in the 1970s. The Glenanne gang was a loose alliance of loyalist extremists allegedly operating under the command of British Military Intelligence and/or RUC Special Branch. It comprised elements of the British security forces who, together with the UVF, carried out sectarian killings in the Mid-Ulster/County Armagh area. Their name comes from a farm in Glenanne, County Armagh, which was owned by RUC reservist James Mitchell; according to ex-RUC Special Patrol Group officer John Weir, it was used as a UVF arms dump and bomb-making site. Weir alleged the bomb used in the Miami Showband attack came from Mitchell's farm. Weir's affidavit implicating Robin Jackson in a number of attacks including the 1974 Dublin bombings was published in the 2003 Barron Report; the findings of an official investigation into the Dublin and Monaghan bombings commissioned by Irish Supreme Court Judge Henry Barron.
