All child abuse needs to be uncovered and punished. Concentrating on a small minority of Catholic priests as the sole perpetrators is taking the spotlight away from far more people that are guilty of the crime.
The above 2 links shed a little more light on the scale of the problem.
This quote from the second link illustrates my point;
"Very few children (less than 1%) experienced abuse by professionals in a position of trust, for example a teacher, religious leader or care/social worker."

For absolute clarity the statistics apply only to the UK and Ireland.
However I would be surprised if the breakdown of the statistics would show much variation worldwide.
