They can and do<quoted text>Prison sentence for what? Churches can marry anyone they wish. Those marriages are only legal if the parties take out a license/certificate from the State. I doubt if any polys would be foolish enough to do that. They can have their church weddings, I don't care.
And I have not seen a lot of arrests for polygamy ( except where not all the parties are aware the other is already married ), I have seen polygamists get arrested for other things, but not specifically for polygamy.
You are right about your assessment of Frankie, he doesnt have the courage to be honest. He hides behind this diversion of the topic instead.
