The death penalty has a good record on recidivism.
The principal arguments against seem to be:-
1. "It's just morally wrong , because I say so".
This is a matter of opinion . Opinions are divided on this issue; an excellent reason for a public vote on the issue. That's how democracy is supposed to work.
2. "It's not a deterrent".
This should not, after so long, be a mattter of opinion. We should have hard data. But if it the possibility of personal death is not a deterrent against aggression, are nuclear weapons a detterent against aggression? If the reasoning is flawed, let's get rid of Trident. One or the other.
3. "We might get the wrong man".
We WOULD get the wrong man, sometimes; there's no " might" about it. If we require 100% perfection of every other government administered scheme, we better shut down the NHS and the DWP tonight, because they kill the wrong people sometimes , too.
4. "It's inhumane".
Again, a matter of opinion. For me, keeping someone incarcerated in pretty unpleasant conditions for life is rather worse. Not everyone will agree, but I wonder how many of those have spent time inside?
5. "If we realise we executed the wrong man we can do nothing. If we jailed the wrong man, we can give him his life back".
No. We can't. His life is screwed. Sure, he's alive. It's the only one of these arguments which holds water IMO. Better to get it right in the first place. If airline pilots- or mechanics- got it wrong as often as lawyers and judges, would there be an airline industry? What actually happens to those who miscarry justice? Jail? Fines? Knighthoods?
I find myself wondering- why this ultra cautious, moralistic attitude in this single area of society?
We build roads, knowing people will die on them.
We send soldiers to war, knowing someone might get killed.
We give policemen guns and tasers, knowing someone might get shot.
Let me suggest a possibly less morally upstanding reason for government's- and the legal profession's - reluctance to execute anyone.
Incompetence- possibly allied to cowardice.
Is the legal system competent to make life and death decisions? The kind of decisions airline pilots, bus drivers and surgeons make every day?
I really don't think it is.
I think it needs a major shake up.
I also think it - and we- need to face our responsibility.
We send young men to Afghanistan to shoot people and to risk their lives, in pursuit of some nebulous goal. Do we actually know anything about who they kill? Do we know they got "the right man"?
When faced with the Harold Shipmans, Bradys and Hindleys produced by the very society those soldiers are killing strangers to uphold, should we not be willing to take the same responsibility for our judgement that we demand of a nineteen year old soldier?
