Hi LogCon, If I were the JWs, I would try to shelter my money in off-shore account(s) that the Canadian government could not access, I would have my attorney investigate how seriously the local prosecutor's office pursues fraud cases, and research where and when I should move to another country.
If I were you, I would find out what ties the JWs have in B.C., what motivates the local prosecutor's office, what is the range of potential sentences for this type of fraud, and if convicted where would they serve their time. I would use all of the above information to pressure them to make restitution, as well as inform the police, local news media, and KH of their fraud.
Peace be with you and everyone, who you love,
Robert
