I found this statement from a recent article about ISIS to be quite interesting in view of the way that any JW can be accused of apostasy with little or no possible repercussions or consequences for the accuser:
In Islam, the practice of takfir, or excommunication, is theologically perilous. “If a man says to his brother, ‘You are an infidel,’ ” the Prophet said, “then one of them is right.” If the accuser is wrong, he himself has committed apostasy by making a false accusation. The punishment for apostasy is death.
Imagine if JWs had THIS policy in place? It would make a lot of elders think twice before accusing or even insinuating that a person was guilty of apostasy.
