===if you mess with a kid your life is over buddy, no exceptions. Mandatory death penalty.===
You are giving the perverts a sound reason to kill their victims. No witnesses means no witnesses.
For years I have believed that the death penalty for kidnapping should be reduced. Perhaps, repeat, perhaps, that might save some children from a pragmatic decision by the perp to kill every victim. If you already have the death sentence hanging over your head for kidnapping, what do you have to lose by killing the victim?
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.
