I personally knew a JW sister years ago who went to prison because she obeyed the Bible/org's rule that a JW could not swear on a Bible in court if summoned to be a jury member.
Her conscience wouldn't allow her to pay a fine as an alternative to prison, but a wealthy JW family got her released after paying the fine for her.
Mr. Whacko-Jacko of the WitchTower Babble & Trapped Society must have missed what Jesus said about not swearing.
