There is a lot more to this kind of offence, the Judges can only sentence within the Law as it stands now. There are people who say they should be castrated either surgically or by chemicals, but do not understand that this does not solve the problem because the offenders find other means with which to get the gratifcation just the same.
Also, and this is no excuse for the offenders in any way, but have you seen the way young girls from 6 and 7 years of age are dressed (in public), it makes me feel sick, they look like miniature adults in totally inappropriate clothing. Everyone says that these sick individuals are around and looking for targets and still these little children are made so that they attract the males in our society.
In Victorian times and in the time up until the 1980's onwards children were dressed as babies and as children, not ever as miniature adults.
Also don't forget the women paedophiles as well and they are around, they make me even sicker at the thoughts of them.
