Whilst I share no sympathy with the guy at all, (he will probably sue the prison for failure to protect him.)
I think you guys really need to get a grip on the whole sex offender issue. With people pushing for the right to know about sex offenders in their area do you know that an 18 year old can and will be prosecuted sentence for having sex with his 16 year old girlfriend even if she approves, if the girl's parents decide to bring the case to court.
Or what about an 18 year old and a 15 year old who are in a relationship. This happens and the boy/man is a sex offender and is placed on a sex offenders list. Should he be brutalised in prison? Given the lethal injection? Shot in the head? Where would you draw the line? 15 years and 11 months, 16 years, 17 1/2 or make it 18? Or would you say consentual sex between boy and girl should be made legal?
If me the labelling of people as sex offenders is a grey area.
