American law can trace it roots through English Common Law and even Ancient Roman Law (most of which was written before the Romans encountered that pesky group of people between Tyre and Egypt who refused to include the worship of the Roman gods).
I could find no mention of what else the Mountain City Courthouse has in their display of American Law other than articles that say they do not know either.
Only three of the Ten Commandments are found in US law (no killing, stealing, or bearing false witness), and those three rules are found in the laws of nearly every civilization on this planet, even those that existed before the Ten Commanments were recorded or heard of.
There have been "Blue Laws" in the past, but most of those are gone, so maybe a fourth commandment came into play, but some of those Comandments are downright unconstitutional.
I don't get this at all... :( I thought it was ruled that NO gov't buildings, like courthouses, could display religious materials, such as the Ten Commandments? :O So, how the heck does this courthouse get away with it? This man shouldn't have to protest or want signs cautioning that we don't live in a religious theocratic country. IMO, the local authorities need to remove the Ten Commandments or any other religious "decor" from their premises. What do you think? Haven't we debated this often in the past, and courts ruled that no religious references were allowed on courthouse walls?! I guess there are a lot of gov't courthouses/buildings still in violation...
