A Lebanese gunrunner is murdered, and the most likely suspect is Ian O'Connell (Anthony Heald), an Irish Republican Army terrorist. This poses a dilemma for detective Logan (Chris Noth), who wonders if his own pro-Irish sentiments may prevent him from conducting an impartial investigation. Originally scheduled to air on January 22, 1991, this episode of Law & Order was bumped forward to March 26 of that year (curiously, only nine days after St. Patrick's Day). ~ Hal Erickson, Rovi
