I first encountered Roy Moore in 2002 in a Montgomery, Ala., courtroom, where I was an expert witness on the separation of church and state in what came to be known as the Alabama Ten Commandments case.
Moore, then the state’s chief justice, was the defendant. He had installed a granite block emblazoned with the Ten Commandments in the Rotunda of Montgomery’s Judicial Building, declared that the event marked “the restoration of the moral foundation of law to our people and the return to the knowledge of God in our land,” and then refused to allow any other religious representations in that public space.
