I don't agree with capital punishment unless in the case of a mass terrorist for public safety.
However I do think that sex offenders shouldn't be kept away from the rest of the prison population. They chose to do the crime so they have to accept what will be dosed out to them.
I'm sure a father in prison or any man with half decent principles would probably hurt him badly.
You don't see prisons keeping gang members safe in prison from other gangs, so why do sex offenders get specialist treatment?
I'd love to have all these serial killers, serial rapists and paedophiles all on a deserted island and do what they like to each other away from the general public.
If it was my child though I would really hurt them.
