The first I heard of the Walsh trial was when we studied the book "Jehovah's Witnesses in the Divine Purpose (1959)". This would be in the early 1960's I guess. I never read anything about it in the press, despite it being held in Great Britain and the case reached the House of Lords. So all I knew was the very selective account in that publication.
It wasn't until I joined this site some 12 years ago that I read the details of it including the transcript. If only we had the internet back then!
