”No solution has ever been found to the problem of what to do with sick people who commit crimes“

Well Jim, we have what we have. Capital punishment is, AFAIC, out of the question - State-sanctioned murder is no better than any other murder - but people, especially children, need to be protected from those who would abuse them and take their lives.

Brady never harmed anyone after his conviction, he spent the rest of his life in what was effectively his prison. I’m not so sure that Hindley died in prison, she was very close to parole when she mysteriously and suddenly ‘died’, and I’ve always held a strong suspicion that, in order to avoid the public outrage that granting her parole would have caused, she was spirited away and given a new identity and a new life (but I have a suspicious nature anyway, so I could be well wide of the mark on that).

Whatever, whole-life detention for those who abduct and murder children seems a reasonable solution to me.
