By SHAWN POGATCHNIK The Roman Catholic Church in Dublin covered up decades of child abuse committed by priests because bishops wanted to protect the church's reputation at the expense of victims, an expert commission reported Thursday after a three-year probe into previously secret church records.Abuse victims said they welcomed publication of the probe into the mishandling of 1975-2004 child-abuse cases in the Dublin Archdiocese, home to a quarter of Ireland's 4 million Catholics.
