I don’t see the 10 Commandments there. It is the Roman Numerals 1-10. There is evidence that it represents the Bill of Right.
Many claim that the Ten Commandments appear several places at the Supreme Court Building but the fact is nowhere at the Supreme Court does the TEXT of the Ten Commandments appear which to me it seems that they don’t place a lot of importance on them.
BTW also there is Mohamad carrying a Koran.
