It's an utterly horrific story. Really appalling.
How was this lowlife ever allowed near to the poor baby?
However, I would still never reinstate the death penalty even though I can fully understand the sentiments behind the suggestion. Miscarriages of justice do happen and the danger of the state sponsored murder of innocent people is just too great. That will never change and it will not be possible to set up sufficient safeguards to eliminate the possibility. Therefore it must remain off the table.
This scumbag should be imprisoned with a whole of life tariff, no possibility of parole and no leave to appeal (as there seems no doubt at all over his guilt here). That is a sanction available in this country and in such cases the judiciary should be willing to use it.
It's not that I think scumbag deserves to live, he doesn't and I certainly would shed no tears over him if he died. I do think that he deserves to suffer every single day for the rest of his useless, shitty life. That can be achieved in prison if the correct tariff is imposed.
