Kenneson noted this observation, albeit six years ago It must be remembered that Joseph F. Rutherford and seven associates of the Watch Tower Society were sent to prison on June 22, 1918, most with sentences of 20 years. Their convictions, however, were reversed on May 14, 1919.
I don't have time to find the reference material at the moment but it is not accurate to say "Their convictions, however, were reversed". The trial had gone on in time where it was not deemed useful to continue in view of some challenges presented of (wrong or inappropriate ?) testimony so the charges or case was simply dropped. Other references by the society suggest "Later, they were completely exonerated of the false charges against them" and this too is not accurate. Apparently the idea of exonerated is not within the realm of what happens in court cases. Wish I could have had the original info because this presentation of material seems a little dodgy. I just wanted to include it in view of what I had learned from the earlier reference material on this matter.
