I was reading this thread and I have a story to tell about this.
Back in the late 70s, a young sister I knew committed fornication with her boyf - once. Riddled with guilt, she confessed to the elders. Brought in front of a JC. She was early 20s and the three elders - one in his 40s, two elderly. One of the elderly bros had recently lost his special pioneer daughter in road accident.
The questions they asked her. I couldn't put them on here. She said she was sobbing her heart out and they were interrogating her with the most disgusting questions. They wanted a minute by minute detailed description of everything. They even wanted to know (why?) what kind of underwear she was wearing!
She wasn't DF but get this, three months after her JC the elder in his 40s was DF. The whole time he was interrogating her at her JC, he was sleeping with another brother's wife! And one of the other elders, the one who had lost his daughter, came up to her after a meeting and said it was her that should have been killed in a car accident not his lovely daughter who was strong in the truth -- unlike her. My friend ran out of the hall crying.
My friend left that congregation as soon as she could and never came back.
