I know of a cousin (then JW) who was molested by her uncle (non-jw).
A friend of mine (then non-jw) was sodomised by an older step-brother (non-jw).
I know a couple of young sisters (jws) who were molested by a friend of the family (jw).
So that's 2 out of the organisation versus 1 case in the organisation.
The point is, cases of sexual abuse are not greater in number amongst the JWs compared to other religions. I'm yet to see any scientific study that proves otherwise. The only difference is that we know that JWs were discouraged to seek police assistance in dealing with the abuse.
