IN 1922 the RUC shot dead three nationalists in the North Antrim town of Cushendall. Many locals believe the killings were carried out in retaliation for the IRA execution of British cabinet Minister Sir Henry Wilson and have tried to uncover the facts of the case for years. One of those who campaigned for the truth was Donegal man James McAlister. Sadly James passed away earlier this month, before his quest was finished. Another of those involved in the campaign to find out why the RUC murdered three unarmed nationalists is Belfast man CHARLIE HILL.
