The 'Nottingham murders' killer wasn't actually convicted of murder, he was convicted of manslaughter on the grounds of paranoid schizophrenia and placed in a secure mental facility. That decision is now being appealed, but this is what happens with death penalty supporters. They all claim that they are only in favour of it when there's absolutely no doubt, but when you drill down just a little bit into examples of cases they want to see the death penalty for, you see that they have very little concern about wrongful convictions and are in fact simply driven by revenge and bloodlust. This is a case with clear doubt, and yet you've already put a bullet in his head. So yeah, in all these cases, the death penalty is not appropriate, because like every other case, there is always a risk of wrongful conviction. That is a principle that is worth clinging on to, even if it means that occasionally we're paying out money to keep some cunts alive (which is basically what
all prison sentences are anyway).
Perhaps a more interesting question would be why would you be happy to have killed
all of these innocent people for the sake of a few quid?
