I'd be a bit concerned if Dearborn (MI) put something like that in their courthouse, but my objections would be the same as to those who make the "out of Africa" argument about Hellenistic civilization. That's why I scoffed at Michael Jackson's video in the Nineties showing the Pharaonic Egyptian court as being black, with Eddie Murphy playing the Pharaoh.
My objection in this case would be based on factual inaccuracy.
You're a rebel, here's your cause:
In 1929, Chief Justice William Howard Taft persuaded Congress to authorize the construction of a permanent home for the U.S. Supreme Court. Construction was completed in 1935, and the Court finally had a home to call its own after 146 years of existence. Sculpture figures prominently in the Corinthian architecture of the Court Building. One chamber features a frieze decorated with a bas-relief sculpture by Adolph A. Weinman of eighteen influential law-givers. The south wall depicts Menes, Hammurabi, Moses, Solomon, Lycurgus, Solon, Draco, Confucius and Octavian, while the north wall depicts Napoleon Bonaparte, John Marshall, William Blackstone, Hugo Grotius, Louis IX, King John, Charlemagne, Justinian and, you guessed it, Mohammad.
