As far as concerning contacting various agencies, I have no personal knowledge of single conviction(other than police agency) from anti-Watchtower activities. That being said, I have been wondering if we have been rather shy on this area. I have some personal experiences of working with the CPS and other agencies on Watchtower abuse cases. I can't disclose any more info publicly yet but will PM you(LV101) for detail info.
Anyone who knows Watchtower abuse cases(sexually, emotionally, mentally, physically, negligent) should contact the local Police, Child Protective Service, FBI, and/or any related agencies. If victim is an elderly, there are a special hot line for it. Infomant will be remained as anonymous. Your identity is protected by law.(in the US)
