I know of a sister that premeditated having sex with a "worldly" to "free" her to remarry and all she got was a private reproof. She bragged about it later that she got away with murder.
Another sister I know of was sleeping with a worldly guy for months and no one ever found out about it until she moved. She didn't even get a JC over it.
I also knew an MS that went on a trip to another country with a sister for 3 weeks, shared hotel rooms etc, they were bf/gf so it would be pretty dumb to think they didn't screw around. He came back and no one found out, after a year, he was removed as an MS, but that was it, no action taken.
If that is just my congo, there has to be hundreds of thousands of others getting away with "wrong doing". Hypocritical behavoir at it's best.
