Reviewers of the case differ as to whether there was a deliberate plot to conceal Smyth's behaviour, incompetence by his superiors at
Kilnacrott Abbey, or some combination of factors.
Cahal Daly, both as
Bishop of Down and Connor, a diocese where some of the abuse took place, and later as Cardinal
Archbishop of Armagh, is recorded as having been privately furious at the Norbertine "incompetence". Smyth's activities were investigated by the
Northern Ireland Historical Institutional Abuse Inquiry, finding that: "..despite knowing his history of abusing children, the Norbertine religious order moved Smyth to different dioceses where he abused more children.." In 2010, Daly's successor as Roman Catholic Archbishop of Armagh, Cardinal
Seán Brady, faced "huge pressure to resign" after he admitted that in 1975 he witnessed two teenage boys sign oaths of silence after testifying in a Church inquiry against Smyth. Survivors groups saw this as evidence of collusion, but Brady said he "did not have the authority" to turn Smyth in. On 17 March 2010, the Deputy First Minister for Northern Ireland,
Martin McGuinness, called for Brady to resign. In 2013, some of Smyth's alleged Rhode Island victims between 1965 and 1968, both male and female, called for the Diocese of Providence to investigate Smyth. As of 2019, Smyth is among those listed by the Diocese of Providence as being "credibly accused" of committing sex abuse. Module 6 of the 2014-2016
Northern Ireland Historical Institutional Abuse Inquiry is dedicated to Smyth's crimes in Northern Ireland. ==Dramatisation==
