That was the same cult. That raid shows how hard it is to stop this group, especially where there is a large Mormon voting block. New strategies have been devised to help in this daunting legal challenge of stopping a child rape cult that is large, rich, and powerful.
"After the Short Creek raid, the Mormon polygamist colony at Short Creek eventually rejuvenated. Short Creek was renamed Colorado City in 1960. In 1991, the Mormon fundamentalists at Colorado City formally established the Fundamentalist Church of Jesus Christ of Latter Day Saints (FLDS Church). The members of the sect did not face any prosecutions for its polygamous behavior until the late 1990s, when isolated individuals began to be prosecuted.[15] In 2006, FLDS Church leader Warren Jeffs was placed on the FBI Ten Most Wanted List; he was arrested and convicted in 2007 of being an accomplice to rape for performing a wedding between a 19-year-old man and his 14-year-old cousin."
That's the way it must be done under our legal system. There are no group crimes, just as their no group rights. Individuals commit crimes and have rights. So you have to go after the guilty individuals, in a court of law.
The innocent, well last I looked they have rights too, and the cannot be punished just because they might sympathize with the (presumably) guilty.
Of course the "child" part of all this is probably a result of the violation of the first amendment rights of the early Mormons, thus causing the breakaway sects that then devolved into these "forced marriage" and "child bride" practices.
I don't like polygamy, and I don't think it produces a healthy society. But it probably should not be illegal, as long as it only involved consenting adults. Marriage is, or was, as much a religious matter as a legal one. It's not been that long since it was strictly a religious matter, at least as getting married. States did not even record marriages during the early years of the Republic, let alone require a "permit" or license.
