My ConLaw professor argued the case before the Supreme Court this morning.
I personally feel that it's fine for the State to put up a memorial honoring religion, but if they do it they have to make the good faith effort to honor all religion. If you want to make a secular statement about how one should live one's life, that's fine too, but then it should be a secular statement, I'd have no problem with a big sign saying, for instance, "Thou shalt not kill" but it needs to be a secular statement and I'm not sure how "I am the Lord thy God" isn't a purely religious statement, it's an instruction on how to conduct your religious life.
