The Utah County Attorney's Office may have raised eyebrows when it declared in a court filing that it would not, as a matter of policy, prosecute polygamists under the state bigamy law unless some form of abuse, violence or fraud were involved. In Utah, this makes practical as well as legal sense.
Polygamy as practiced by several of Utah's fundamentalist Mormon clans is pernicious. It enslaves women from girlhood in a patriarchal and religious web that denies them education, reproductive freedom, self-actualization and career opportunities. It can be equally corrosive in the lives of boys.
But there are exceptions. When consenting adults enter into religious marriages that are polygamous, without the expectation of the benefits of the state's legal sanction, and there is no fraud, violence or abuse involved, there's nothing to be gained by prosecution.
