On July 24, 2008 the United States Senate is holding a hearing in front of the Senate Judiciary Committee regarding the FLDS Church and the polygamist lifestyle. Only the only people invited to help the Senate understand this group are people who are hostile to them. This committee has no intention of hearing both sides.Petition protesting this here.
You should also call and/or try emailing your Senators, especially if any of them are on the Judiciary Committee. It will mean more to them to hear from their constituents.
And let me point out that in 2005 when Hilderbran of the Texas state legislature got it into his head to do something about the FLDS, he targeted all homeschoolers. An ounce of prevention is worth a pound of cure, and one needn't believe the FLDS lifestyle is all tulips, roses and God's daisy chains in the sky to see that if it's acceptable to the Senate to investigate one religious group and not even seek to hear from members themselves, others will follow.
In case you were wondering, this contradicts the rights allowed in the First Amendment.
