I don't take it as haranguing. Not at all. These are quite long, complex exchanges (that I'm enjoying, by the way), and unless we treat each post as a professional project, drafting and redrafting (and I sure don't) it's easy to miss touching on each and every point.
Also, for clarity, my jury service was also ages ago (30 years-ish), and not on earth-shattering issues either. Certainly not ones that would have been life sentence, let alone DP cases. Nonetheless, the burden of being potentially responsible for banging someone up, never mind their execution, was one I took seriously. It weighed quite heavily, and so it should on anyone that's ever done it. I don't think people can quite understand it, if they've not done it. I mean, they can understand it intellectually, but never quite feel it.
For instance, it's easy to judge on news reports, TV clips, newspaper articles, etc, and be 'sure', just as it's easy to be a keyboard warrior and threaten to punch someone's lights out, but not as easy when you meet them face to face, and find out you're an average, overweight, flabby-reared office worker, and you've been threatening a young, extremely fit special forces soldier. Most of us are martial arts experts only in our own fantasy worlds. Some aren't. Then, the reality of the situation comes home to roost.
But unless you've psychopathic tendencies, or are at least emotionally stunted or atrophied, the reality sets in when you realise, in the real world, that person, that real person, with feelings, hopes, family, etc, sitting 30 feet from you in the court might spend the next several years in prison because YOU decided as you did in the jury room.
Personally, I rather hope I don't find myself in that position on a life case, or LWOP case, let alobe a DP case. But if I did find myself in that situation, then I'd discharge my duty and responsibility as best I coukd. And my stance on the DP is with that borne in mind. It's the mindest in which I take my view on the DP.
As for those specific questions, I thought I did answer the first, albeit kinda metaphysically. I can't even be sure the world exists as I see it. You, and everything else I experience, MIGHT be a figment of my imagination and reality is I'm in a drug-induced fantasy, or a psychotic episode in a padded cell, or a 30th Century Matrix VR world on humanity's first colony in the Andromeda galaxy.
So, a simple, direct answer to 1) is no, since I can't be utterly, totally sure of anything at all. But I can be utterly convinced I'm not in a psychotic break, or Andromeda. Of course, there's an extremely small possibility I'm convinced, but wrong.
And bear with me, there's a point to all this. And I'm getting there.
On point 2), I'm going to give a somewhat politician-type answer.
I think the question is the wrong question.
It's not whether the price is worth paying, but whether the sentence would be right, or wrong, in the circumstances.
In ANY jury decision, there's ALWAYS the chance you get it wrong. But it's a balance. There cannot be absolute certainty (hence q1 being easy to answer). But the only difference is the degree of injustice, not whether it happens at all. And that's why we have a presumption of innocence, and beyond 'reasonable' doubt.
You mentioned the Guildford 4 and Birmingam 6. Let me ask this. Can we ever give them those missing years of life, the years they spent incarcerated, back? Perhaps in a sense more importantly, can we undo the loss innocent family members suffered?
No.
Yet our system allows that risk of misjustice anyway.
The system goes quite a long way towards avoiding punishing the innocent, including when it means not punishing the guilty.
So, let's look at the DP another way, and at least, bear this in mind. First, context. Given that I'm not particular familiar, as I said earlier, with the individual this thread started on, I did stipulate, when this thread got to be a more serious DP discussion, that I was referring to "the worst" paedophiles. Given that all paedophiles are pretty obnoxious, let me nail that down a bit. The "worst" I meant are the really, REALLY nasty ones, sexual sadists fixated on kids, for instance. Any victims of a paedophile are likely to pay a mental price for years, maybe life, but some carry physical scars, or don't survive the experience.
So, when rejecting the DP, yes, you MIGHT prevent a miscarriage and hence the execution of an innocent. But you WILL prevent the execution of the guilty, and therefore, run the risk that one of those guilty paedos is subsequently released, or escapes, and goes on to abuse, maim or kill more innocent kids, before getting caught again.
So, yes, I understand the point you make about possibly executing an innocent person. Just don't make the mistake of thinking that not having a DP means you have no chance of the innocent not suffering or dying, because we don't.
There is no perfect solution, either way. There is NO method by which we can absolutely guarantee that the innocent never suffer unjustly. Either way, there's risk of that.
It's life, I'm afraid. At one end of the spectrum we have the law of the jungle, survival of the fittest. That, essentially, is when we get the Saddam system of justice. I regard UK justice as far more 'advanced, more 'civilised' than that, and we have a system, including checks and balances, and a presumption of innocence with a bar to conviction set pretty high. But make no mistake, the price we pay for setting the bar quite high to protect innocent from conviction is that quite a few that, in reality, were guilty, go free.
It is an admirable moral position, to protect the "innocent" from conviction, but make no mistake, that "admirable" position DOES result in nasty people going free, and genuinely innocent people ending up as victims because we set the bar that high. Yet, society makes that judgement, sets the bar that high and, pays that price.
Get it wrong with truly guilty "worst" paedophiles, and it'll be their future victims that pay the price. Are YOU prepared to pay that price, by opposing the DP, when executing such "worst" paedos would have saved those kids from what was done to them?
Uncomfortable thought, innit?
So yes, in answer to 2), whatever system we devise, there will, short of the future development of a 100% accurate and reliable truth detection system, always be a very small risk of executing an innocent. Is that a price worth paying, you ask? Yes, provided we do our very best to make the system as foolproof as realistically possible. Because there is also a risk from not doing it.
It's a balance. No system is, or probably ever will be, perfect. Right now, we lock people up sometimes for decades, and cannot undo that any more than we could unexecute people. Yet, we take that chance. It's the inevitable result of not having a system that was perfect.
If we don't execute a paedophile, or the worst of killers, then if they ever get out of detention and kill or abuse again, the system bears responsibility for that suffering.
How strongly do we weigh the rights of the worst paedophiles, against whom a hugely strong if not 100% guaranteed case exists, compared to the rights of the innocent kids that will become victims should they get out?
I can almost hear a chorus of "lock them up for life, then". Well, to bounce q2) back at you, can you be 100% certain that, even if you sentence them to LWOP now, that a future court, panel of doctors and/or parole board won't decide they know better? And who's better equipped to judge guilt .... a judge and jury that have just sat through the trial, or some 'review' board in 10, 20 or 30 years time, when they read the file?
I understand your concern, opel. I'd ask you to consider, though, that there's risks to the innocent either way. The DP is utterly pragmatic in one way, at least. If you execute the "worst" of these offenders, then and only then can we know, 100% and for certain, they won't harm any future truly innocent victims.
If we have a DP, there's a small chance of executing an innocent in a miscarriage. If we don't, there's a chance of the guilty notching up further victims. At least, if we have a DP, we can truly attempt to devise a system to minimise chances of miscarriages, but it's a fact of life that no system can guarantee no miscarriages, in both directions. Life is a risk, a balance, a compromise, and the best we can hope for is that we genuinely seek to do the best we can, and minimise mistakes, and get that balance in the right place.
We could draw the conclusion that rare mistakes in the DP means we never execute again, but by that logic, the lesson from the Guildford 4 and Birmingham 6 is that we never lock anyone up again, in case we get it wrong. In which case, we're back to law of the jungle, and in all likelihood, vigilante justice.
Balance, compromise, genuine best efforts. That's the only thing we can do, imperfect as it may be.
