For my two-penneth....
Mis-carraiges of justice in the history of trials for murder in this country are very few and far between.....Stefan Ivan Kiszko, Derek Bentley, The Birmingham Six (admittedly no death sentences but incarcerated,albeit wrongly for a long time,) ...but if you look at it constructively throughout the history of our Judicial system...the total figure of those wrongly convicted of murder,is a very minute and miniscule fraction compared to all the people convicted rightly and correctly of their crime of murder.
In this age of technological advances, forensic evidence etc, surely we would be better taking the " death row " stance, incarcerating the indivual concerned.... until the crime is proven beyond all reasonable doubt.
Admittedly a timescale for proving the matter beyond reasonable doubt would still be contentious. What sort of timescale would be set ??? One year??? Two Years??? Five??? Ten???
But once their guilt is proven, then we get to the sticky question of how we carry out the death sentence...
Hang them ??? Give them the Chair ?? Lethal Injection ???
One thing is for sure, As a country, there are far too many people who concern themselves with the well being ( human rights ) of criminals, who have (when comitting their crime) clearly shown a total disdain for the "human rights" of their victims. So as a society, why is it....people who can "defend" the actions of mindless, evil and heanous criminals get more of a say than the families of the victims???
I'd hate to think of what sort of justice that the families of the victims would want??? Eye for an Eye, Tooth for a Tooth and all that.....
People like Huntley, Brady,etc,etc make me sick to the pit of my stomach. Why are we taxpayers, paying an absolute fortune to pay for the security / well being of these folk??? More to the point, why are the security (prison guards etc ) forced to spend time watching these wastes of fresh air and preventing them from taking their own lives???? Hand them the pills, give them their own rope / sharp implements....cut off their food..let them get on with it.
If they ever recruit for the position of official executioner in this country, I'm sure they won't be short of applicants
So, summarising, keep them on / in a death row situation, until proved beyond reasonable, doubt and then get rid!!!
