As many of you may know, the U.S. Constitution Amendment 1 of the bill of rights says that Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
The U.S. Constitution doesn't say anything about the local states or governments doing so. That's my $.02 worth and YMMV.
