There is no deterrent for a child molester. They can't be reasoned with, and they can't be fixed; it's a problem in the wiring. They need to be put down, humanely, if possible, to avoid any further victims. It's not about deterring them. All we can do is mop up the mess they leave, and make sure they can't do it again.
I agree with you about the need for total protection from the threat posed by those perverts; but believe that capitol punishment should be reserved for murders and treason.
One of the side effects of capitol punishment is that it is a political magnet and cash cow for lawyers and liberals. they have a power source because of that issue.
I don't like their mixing druggies, kidnappers and perverts in the same prison either. Keep them in a like population....they're learning too many things in those institutions of higher criminal learning.
I'm getting cynical in my old age.
