The five-volume, 2,500-page report of the government-appointed Commission to Inquire into Child Abuse in state-funded Roman Catholic Church-run institutions dating back to the 1930s, is displayed following a press conference at the Conrad Hotel, in Dublin, Ireland, on May 20, 2009. Sexual abuse of children was "endemic" in boys' institutions in Ireland and church leaders knew about it, a major report on mistreatment in church-run bodies dating back to the 1930s said Wednesday. "Sexual abuse was endemic in boys� institutions," said the long-awaited major official report, adding that: "Sexual abuse was known to religious authorities to be a persistent problem in male religious organisations."
