They use the two witness rule to their liking. If a JW wife tells the elders that her husband confided to her that he committed adultery yet refuses to say that to the elders, the elders can decide to accept her word for it and she would put into writing that her husband was an adulterer and she could be scripturally
free to remarry if she so desired. Only one person has come forward. There are no two witnesses, yet that is acceptable??? Yeah right!
