I agree MOnica- but I'm finding this thread very strange.
Lots of parents have children who are criminals and it isn't necessarily their fault.
There is an assumption here that handing over your child is something wrong, like some unwritten parental rule that your children must be supported by you whatever they've done.
The Kray twins spring to mind- who always treated their mother well, apparently.
I'm also thinking of Jimmy Saville, likewise.
A crime is a crime is a crime, and it is against the law. It is the judge who pronounces sentence, not the parent. If you don't agree with the death penalty for your child (and who in the right mind would?) then you shouldn't believe in it for anyone elses's child either.
These issues lie at the heart of the struggles the US (and to lesser extent here in the UK) are dealing with right now- that it's ok when it happens to someone else but not to me. When we realise it is happening to me (or even thinking it might, as seems to be the case here) then we feel uncomfortable about it.
This is because killing people, whatever the means, is wrong. At least on that I hope we can all agree, excpet if you think it's ok to execute people, in which case it should be ok, however unfortunate it may be, to execute your child.
