They are in violation of the law; they just cannot be prosecuted by it. US FLAG CODE IS LAW; however, it only applies for prosecution to Federal and State Agencies.
The Mayor of Nauvoo, John McCarty, contacted the Mormon authorities in Nauvoo today, Wednesday, January 30th. The local Mormon authorities said that Salt Lake City called them and ordered the US Flag to be lowered to half mast. The Mayor of Nauvoo told them they were in violation of US Law. The local Mormon Authorities refused to restore the Flag to full mast and said they would call Salt Lake City. The local Mormon authorities called the Mayor back at approximately 3:00 pm and said the Attorney for the Mormon Church said they would not restore the US Flag to its proper place that the Mormon Church was exercising their 1st Amendment Rights. Their 15th "Prophet" died last Sunday and they have every right to mourn his passing; however, mourning doesn't give anyone license to defy the laws of the United States.
Monday February 4th the Mormon Church will commemorate their "Exodus" from Nauvoo in 1846. They will present rewritten history to promote their story that the reason they were expelled from the State of Illinois was religious persecution. This is not true. Accurate history shows the Mormon Church leaders were in defiance of US, Illinois and Hancock County Law, and that is the reason for their expulsion. 162 years later, nothing has changed, the Mormon Church still considers themselves above the law.
Fraud and falsehood only dread examination. Truth invites it.
