Hazel - I agree with you about distinguishing between young adults and actual children, it’s an important point. I think an adult who is consistently attracted to much younger people (ie a guy in his 40s who always goes out with 15/16 year old girls) is more emotionally stunted whereas someone aroused by a pre-pubescent child is physically warped (something wrong with brain chemistry or whatever).
I understand where you’re coming from about the walled city. There seem to be a hell of a lot of paedophiles out there. Given the cost of locking them up in prison, and the fact that these people are only a risk to a certain element of society - means an alternative to life imprisonment in the conventional sense may be needed.
People that can’t be rehabilitated should never be let free in mainstream society. We cannot put their rights and freedom above the rights of innocent children, or the rights of any innocent people. I have read studies on chemical and physical castration. These methods do not always (in fact rarely) work. Sometimes if the desire is there but not the means to carry it out, a paedophile will rape or hurt a child with another object instead.
An open prison/electronic tagging is obviously not then a possibility. However a more open-style prison on an island might be. Eg an uninhabited island. This might sound crazy - but it costs hundreds of thousands of dollars per prisoner per year in some high security jails. An offending paedophile’s life is just not worth that expense to society, IMO, when there are so many other deserving causes. Yet in the absence of the death penalty if we are forced to keep the worst cases alive, then yes, let us consider some sort of exile or alternative society for them.
Another issue is that abuse has been shown to breed abuse. If we do not cut it out of mainstream society we will never be able to reduce the problem.
Personally I hope that we can one day find a “cure” - even if it is a form of chemical or physical surgery that effectively mentally impairs the offender further. Anything that can cheaply and effectively control them - or help them control themselves - seems like the best option.
