Allegations of cover-ups of sexual abuse of children by Catholic  priests have now spread to the very top of the church hierarchy, forcing  the Vatican to issue a strident defence of the Pope's role in the  scandal. 
 
Revelations this week that the Vatican halted the investigation of a  Wisconsin priest accused of molesting some 200 deaf boys are now  threatening to ensnare Pope Benedict XVI. 
  Documents obtained by The New York Times this week showed  the priest was spared a defrocking in the mid-1990s because he was  protected by the Vatican office led by Cardinal Joseph Ratzinger, now  the Pope. 
  The Vatican issued a strong defence of its handling of the case,  announcing in its newspaper L'Osservatore Romano that there was  no cover-up and calling allegations of papal involvement a "clear and  despicable intention" to strike at Benedict "at any cost." 
  Gerry O'Connell, a Vatican affairs correspondent, told CTV's Canada  AM that the church has decided to go on a public relations offensive  over the burgeoning abuse scandal, which has also arisen in cases in  Ireland, Italy and Germany. 
  "The Vatican reminds me sometimes of a fire brigade. The fire starts  up in one place and they move there, then the fire starts up in another  place," O'Connell said. "The Vatican feels it has to be more pro-active  to deal with these problems." 
  Senior Vatican officials are determined to defend the Pope's handling  of the issue, O'Connell said. 
  "There's a flat denial that he was responsible," he said. "They say  that when you actually examine it case by case, he's the pope in history  who's taken more action against child abuse … he's given instructions  to bishops in every country to deal with the historical facts, to  operate with transparency and honesty and avoid cover-ups." 
  And O'Connell said that calls for his resignation are unlikely to be  answered: the only time a pope has stepped down was in 1294. 
  "Here there is not any thinking that the Pope will resign … they feel  pretty sure in the Vatican that they can defend themselves."
