Besides Catholic priests there are also Catholic nuns with credible allegations of abuse against children, but it seems like their victims are not getting enough visibility, When the media reports about abuse in the Church it is almost always about the priests. Nuns may be even more difficult to prosecute because women are not seen as abuser in general and nuns are usually out of the media spotlight that is focused on abusive priests.
