Quote from gastropod:
You have the cart before the horse - you are in effect saying, "He went to jail, so he must be guilty." If you read the article - that is one of his points - even in America, you can go to jail and not have been proven guilty. From the article - he was in jail for contempt of court - not giving up more money - even though there were no claims against him. I do not know the truthfulness of that - I am just restating what the article said.
With the above info in hand - yeah, I would probably be a ranting fool too, if I had been beaten in prison...having been in prison for no apparent reason (at least in his eyes).
