Following the Bloody Sunday incident in Northern Ireland in 1972 , in which fourteen unarmed civil rights protesters were shot dead by the British Army , Lennon said that given the choice between the army and the IRA ( who were not involved in the incident ) he would side with the latter . Lennon and Ono wrote two songs protesting British presence and actions in Ireland for their '' Some Time in New York City '' album : " The Luck of the Irish " and " Sunday Bloody Sunday " . In 2000 , David Shayler , a former member of Britain 's domestic security service MI5 , suggested that Lennon had given money to the IRA , though this was swiftly denied by Ono . Biographer Bill Harry records that following Bloody Sunday , Lennon and Ono financially supported the production of the film '' The Irish Tapes '' , a political documentary with a Republican slant
