one time me and another brother caught an elder smoking. told him he had a week to come clean. he did but nothing. caught him again and told him to come clean again. again he did and they did nothing cause he was an elder.
one time my wife found out a sister was working for a strip club. my wife was working part time and some guys she worked with had a bachelor party for one of the guys in the office one weekend. one of the girls in the office the next week mentioned that there was photos going around between the guys from the party. my wife happened to see them and in one of the pictures was a sister in a bikini sitting on a guy's lap. she asked the guys who it was. they all said she was a stripper at the party. she da'd before anything else could be done. she was "on the edge" as it was anyway.
the one that sits funny with me though is we were helping an old sister out with cleaning her house. someone always picked her up and took her to meetings, but she made it clear that friday nights she was to be left alone. turned out, they saw her coming out of a bingo parlor. she played every friday night. went on for years it turned out. well, when one of the brothers approached her about it, she told him it was her own money and her own business and no one else's. sure enough, no one said any more to her and she played every friday
