Ashley Colville, in Teeside Crown Court, (Mail today, sorry no link) has 17 paedophilia convictions. His lawyer explained he had reached top of the list for chemical castration, but everything stopped for Covid (why?)
And, that there was a random lottery of prisons why do, and don't use the treatment (why?)
The article explained that in comparable countries, castration can be made available by either surgery or chemicals, with the latter being less satisfactory because it reverses, as soon as treatment ends. But UK only offers chemical, and only for a few prisoners in a few prisons (why?)
Yars ago I researched this and recall that in those countries where surgical castration is made available, offenders are often desperate to have it, not only because they don't want to spend their lives constantly in and out of prison, but in some cases because, despite their urges, they are revolted by their own actions.
Castration by either method may not completely remove urges,in all cases, but it helps, at least, and at times works entirely.
I also researched the close relationship between violence in prison and unusually high testosterone (in both men and, more rarely, women) Prisoners don't actively choose to be out-of-control violent, again not only because they don't want repeated sanctions and extended sentences, but because they don't like what they realise has happened. They are not offered hormone re-balancing (why?)
Hormone balancing and surgical castration on request would appear to be a reasonable option, which even the leg-crossing men in parliament could surely not mind, since it would not be part of a sentence, only an option for an acceptable future life.
There again, in some countries chemical castration is part of a sentence, in others it may be offered as an option before choosing the sentence, and there appears not to be any particular reason (other than male MPs shuddering hysterically at the very word) why it could not be incorporated into UK law on both sentencing and parole.
Somewhere, a famous man described reaching extreme age and (presumably) a vanished libido, as being "at last, unshackled from the madman" The prisoners interviewed expressed much the same sentiments. Better have a peaceful, free life with no appetite at all, than have an intact appetite which constantly puts you in prison.
But the absence of interest would need to be periodically monitored, presumably by technology (viewing previously arousing images or descriptions, while wired up to an electode covered skull cap?)
