17 years no parole is obviously absurd.
Grace Millane was a willing participant in extreme sex, so Kempson has a legitimate defence. Actions after are realistically explained by panic. The other convictions are propensity evidence of extreme sexual need, not homicide.
At some point you hang em highers should be realistic about the need for extreme sentences.
I have no idea how you're arriving at those beliefs.
Firstly, you (and I) have no idea what was and was not consented to by Millane in that hotel room with Kempson. You only have Kempson's own claims - claims which have been fundamentally contradicted by the evidence in many respects.
And in any case, irrespective of what Millane may or may not have consented to, all notions of consent go out of the window the moment she goes unconscious. There is zero chance that Kempson could somehow have
missed observing that Millane had gone limp, had stopped interacting in any way, and had closed her eyes. Yet he must have continued holding his hands to her neck for a considerable period of time beyond that point, in order for her to have experienced brain death at his hands.
Secondly: as for your "actions after are realistically explained by panic" claim, I fundamentally disagree - as did the court. I've explained previously in this thread precisely how/why I (and the court) fundamentally disagree with your view here.
Thirdly, it's a generally-accepted psychiatric belief that wrt crimes committed by males against females in the areas of rape, sexual assault and domestic violence, these are expressions of power, control and dominance first and foremost. Any sexual elements are subordinate. So I don't think you'd be able to find a single respected expert in this field who would profess the opinion that "extreme sexual need" was at the core of any of Kempson's offending.
And lastly, I most certainly don't regard myself as one of the "hang them high brigade". Kempson committed a string of crimes which were right up at the top end of the tariff for seriousness and extremity, at the top of which was the Millane murder. I am personally wholly satisfied that Kempson was correctly convicted of the Millane murder (though I do not know enough about his other convictions for rape and sexual/physical assault to form an opinion on their safety). I think Kempson got the correct sentence for the Millane murder (and I mean "correct" in two ways: 1) in the sense of the sentencing structure of the NZ criminal justice system, and 2) in the sense of what is deemed appropriate by jurisprudence views in modern liberalised democracies).
You might or might not also have noticed the final sentence of my post: I wrote
"It sounds like an awful lot of work will have to be done with him before he's anywhere near being considered safe to allow back into the community." In my opinion, this man's convictions show that he is a very great danger to the public (and specifically young adult women). Part of the rationale for incarceration of offenders is public protection, and I would say that Kempson would rank as one of the most dangerous people currently in prison in NZ. But there's still the possibility of him being provided with the right sort of counselling and offender management while he's in prison, such that he might eventually return to the general population as a productive and law-abiding member of society. I think it will probably take many, many years of expert work to even get close to that point. But I certainly don't advocate anything akin to a "lock him up and throw away the key" approach.
