All paper. Forgive me for not being impressed with such safeguards.
I'm not impressed with them. Polygamy is actively practiced in both Utah and Arizona. There are cities that are known polygamist strongholds, where members of law enforcement are polygamists.
And the official website of Utah Attorney General Mark Shurtleff notes that although polygamy is illegal in Utah (he conveniently forgets to point out that it's prohibited by the Utah Constitution) and against the constitution in Arizona (and against the law in Arizona, which isn't mentioned), he says that law enforcement in both states have decided simply to concentrate on welfare fraud and child abuse. Translation? We're not going to enforce polygamy laws (that would be embarrassing to the LDS Church, because LDS members have to keep on explaining history and how these groups are different from mainstream Mormons). And there are members of the LDS church who are polygamists. It's still a part of their doctrine - Doctrine & Covenants 132 to be precise - despite the 1890 and 1904 Manifestos.
