I don't think this sounds like that kind of scenario at all. I agree those people are probably not treatable, their main problem really may not be their sexual drive, but they seem to have no moral sense at all. So they are willing to do anything to serve their sexual desires.
He is not like the predators I described because he is not an influential billionaire / multimillionaire.
What he has in common with them is that he is a dangerous sexual predator
I see the point you are making as coming down to a few questions, which I don't think you and I have the answers to.
One is whether, in fact, having sex occasionally is likely to actually be helpful to this person. I don't really know the answer to that, obviously as most people have experienced, sexual desire can be very powerful and can lead to bad decision making.
I believe you are making the mistake of thinking that violent rape occurs because of overwhelming sexual urges.
My understanding is that violent rape and stranger rape have nothing to do with overwhelming sexual urges and everything to do with a compulsion to violate and hurt another human being, reducing them to an object. The underlying affect is of hatred and very often of vengeance against someone other than the victim
And then the second is what kind of risk he is. I know the article said he had a higher risk profile, but it doesn't really tell us why,
oh but it does, it tells us this
"Edward William Latimer, 61, has a criminal record dating back to his teenage years and has spent most of his adult life in prison for offences including sexual assaults and wilful exposure."
also
"In 2005, Latimer was sentenced to almost three years in prison for trying to rape a drunk man who had fallen asleep in a park."
and
"Latimer was placed under a continuing detention order the following year until he was finally released in 2014 on a five-year supervision order.
The next year, a judge found Latimer twice breached a condition of the order by sexually propositioning women he did not know, so he was again placed under a continuing detention order until now."
This appears to be a man who, for whatever reason struggles to contain his predatory urges.
My feeling was that he might be someone who suffers from a fairly significant developmental disability and essentially needs supervision like a child would. But that is a guess.
I have no idea whether or not he has a learning disability or some other condition.
Clearly having raped a sleeping man he would pose a danger to men in prison.
He would appear to be an extremely dangerous person who the state struggles to know how to deal with.
If he does have a learning disability or some condition that disinhibits him and makes him dangerous then possibly he should be contained somewhere safe where he can be looked after and does not pose a danger to others.
