We do know that Watchtower has a vey large broom that can whisk away even the nastiest of events.
It is hard to nail down statistics about suicide but ... all I know is that in my first 22 years of life I had never even heard of suicide.
After joining the WT, within 3 months a sweet young man who I knew personally, killed himself. He was being groomed to be more active in the congregation. Don't think they had a name for that then.
As the years rolled on there were more who buckled under the weight of the pressure, guilt and obligation of the watchtower cult.
So just in my former 'circles' of jw acquaintances, I still hear of it.
