I didn't say that or even suggest it. Every crime you have cited above is against the law as it should be. What I find missing from the FLDS mess is due process. If the men committed the crimes being discussed, arrest them, put them on trial and let a jury sentence them.
We shouldn't accept or expect changes in due process because we find one crime more repugnant that another.
They're working on it. They need more evidence. Should they put these men in jail pending trial on nothing? How do you propose they get more evidence? Isn't the testimony of the women who've escaped from there good enough for you? Or the pregnant teens? Or the kids who don't even know who their parents are? DO you not know that they've got serach warrants, as required by law?
Do you not realize that a case of this magnitude takes time? How fast do you think they're going to be able to move on this?
