The answer to this is easy.
1st offense of child molesting - 25 years with no parole.
Set up prisons with military barracks style living arrangements. much cheaper than these semi-private rooms the criminals get now.
2nd offense - death
Problem goes away.
As tempting as that is you really shouldn't do that.Why? One reason (and *only* one reason)..because if you can get the chair for abusing someone then you have no incentive to let that individual live after you've abused him/her.
A guy who was seen taking a leak in the woods at a golf course ended up on the sex offenders list.
A teen who got caught in the back seat of his car with his girl friend ended up on the sex offenders list.
Is that really justice?
