Storm in a teacup. Allow all religious books or none. If a scientologist wants to swear on'Battlefield Earth' that's fine to me. People who are going to lie will do so whether they have a bible or a menu in their hands.
As far as I know all states allow the option of "affirming" that you will tell the truth rather than swearing, on the Bible or anything else.
What's the value of having a muslim swear on the Bible anyway?
(Although having them swear on the Quran doesn't really gain anything as it tells them to lie to "infidels".)
The whole idea of swearing an oath, especially on a holy book, is a hangover from a belief system in place at the time the Constitution was written.
Hardly anybody today, even quite religious people, believe their soul is doomed to eternal hellfire if the swear falsely on a holy book. A couple of centuries ago, an oath like this actually meant something beyond making one "liable to the penalties of perjury."
Anybody know the procedure in Muslim countries or under Sharia?
