Around 4 years back, I belonged to a congregation where the elders were much complacent. Shunning was practiced, but only theoretically. Everyone spoke with them in private.
A disfellowshipped young guy regularly drove the ex-presiding overseer and his wife (both very old- in their late 80's) to the Kingdom hall and back. Funnily, due to some miscommunication, once he ended up picking up a branch committee member and his wife from the airport who had come for a local convention as a speaker. No one made a fuss about this.
Another unrelated incident:
A year later, a Special Pioneer (16 years a SP) was assigned to our congregation. (His photo appeared in one of the JW literature, dont remember which) He managed to put things up and with his influence around a dozen or so started pioneering. A year later, with reasons unknown to me that time, he suddenly stopped coming to meetings altogether and mailed a one liner disassociation letter to the elders. Come what may, he flatly refused to meet the elders and even the CO and the DO. Last I heard, he had joined another weird cultic group he had become fascinated with. This was a jolt to the entire congregation. Till now, he regularly comes to all JW funerals wearing all white which makes him look more weird.
