Here's a quote from an article on silentlambs re the ratio in UK;
"When you consider the number of Catholics in the UK as compared to the number of Jehovah’s Witnesses these are horrific numbers. How many priests are listed over the last four years? According to the list 137 Priests were in court or charged with abuse. When you consider there are 5.7 million Catholics as compared to 137,000 Jehovah’s Witnesses the ratio works out to one Catholic priest molester to 41,605 Catholics as compared to one Jehovah’s Witness elder molester to 5,269 Jehovah’s Witnesses. That helps to show the epidemic proportions of the abuse problem within Jehovah’s Witnesses."
I wouldn't be surprised if the ratio was very high elsewhere too, I've seen fraudsters target the cong because they know they would be trusted and not taken to court if anything goes wrong. It's an obvious place for a peadophile to hide too, access to children, the 2 witness rule, confidentiality and reluctance to involve authorities, unfortunately there are wolves that have exploited that environment and it seems the org. Has not done near enough to protect the congregation.
