Within a 125 miles or so, there's been murder, rape, embezzelment, and what might be termed the more "usual" sins of dumping a marriage mate and taking off with another's.
Many of the above are common knowledge.
When I first became an appointed elder, I was totally blown away by the stuff that was going on that WAS NOT KNOWN or NOT COMMON KNOWLEDGE, but that were major scandals that had not managed to leak out.
I think the fact that Witness congregations have seen such/much scandal, proves that despite what Witnesses think about themselves as being "better" and "above" the average human, they are in fact much like everyone else, perhaps even MORE INCLINED to some kinds of evil (no hell-fire to make them pause, etc.), there's not a surprise that a percentage of Witnesses wind up committing crimes, including disgusting and perverted ones.
My two cents.
