Just a side point - JW are not the only organisation being investigated. Other churches are being investigated, too. One of them is the Catholic church. So if a JW accepts the investigation into the Catholic church as being true, then they would have to consider the investigation of the JW organisation in the same light. The same legal team is responsible for investigating all churches.
I say this because your husband might raise the objection that the JW are being singled out. That is not the case.
