I don't see the point of removing a persons civil liberties just to have the tax payers pay for these criminals existence for the rest of their life. There are much more useful uses for such scum, organ harvesting, scientific experimentation, etc. I think if you take a life, you give up your human rights and the right to live. Also, I'm pretty sure this would be a good deterrent as well, no point being soft, China has the right idea.
