five sisters from Northern Ireland, challenged the Irish Republican Army's code of secrecy and silence after their brother Robert was killed in a brutal bar brawl in Belfast in January. Several members of the IRA were suspected of being involved in and covering up the murder. The women's campaign to hold the IRA accountable reached an international audience and prompted many to question the legitimacy of the IRA, even in Catholic communities that had once been IRA strongholds. The IRA's subsequent offer to kill the men responsible generated further outrage. The sisters were invited to the White House for St. Patrick's Day.
