Dealing with criminals shouldn't be about exacting the most amount of pain possible, that is simply revenge, and vindictive. Killing someone(if it was done somewhat properly) would be far less stressful and horrible than spending 50 years being raped and beaten in prison before dying slowly from something in prison anyway.
Fact is, it can't be done these days, a HUGE reason it costs so much is the people who often get on death row. Sure there are people who campaign hard and work to get people off death sentences, but there are lawyers(on every side) who get paid a crapload of money, and every extra appeal means more hours rehashing the same evidence again with the same outcome with very little real work being done, while getting paid out of a bottomless pit. You can end up with a poor guy, innocent or guilty, being prosecuted by one group of lawyers paid for by the government who get more money for every appeal, and another group of lawyers for the defence, also being paid for by the government, who get more money for every appeal.... We're talking about quite literally billions of dollars in lawyers fee's and no reason they should give up on innocent or clearly guilty people.
You could argue that the extortionate cost in California per person executed would merely drop drastically if they only executed more people
$308mil per person now, kill 10 times more people, that drops, kill 1000 people, its cheaper than a life sentence. I'm mostly joking there.... I think.
Fact is in the overly litigious society, most death row guys spend years, even decades on death row with entire teams of lawyers both defence and prosecution fighting appeal after appeal and that is where all the big costs come from.
The simple costs are, slightly more expensive jail cell for 6 months vs a lifetime in a cheaper jail, its only the legal fee's that turn it into a joke cost wise.
Should we do it, yes, does it deter criminals, yes, a proper death setence, one where most people get off eventually isn't a deterant. if it was much more limited for cases where there are confessions, video, caught in the act only where there isn't any question.
CRAZY says thousands of innocent people have been executed, while saying only 138 were exonerated afterwards, and in this day and age, political agenda's rule more than the truth. If there is a particularly vocal group and no opposition group, what does the state have to lose by giving a pardon? Nothing, yes they can look good by pardoning someone if a group thinks he's innocent and no one thinks he's guilty. Some people are given pardons having done the crime but having been harshly dealt with or given an exceptional harsh sentence. MANY GUILTY people are pardoned if someone thinks they are worthy of it. Exonerated or pardoned does not automatically confirm without doubt they are innocent.
AS for thousands, we've killed 150k+ people in Iraq now, a crapload more in Afghanistan, of which a huge portion or completely and utterly innocent people, and this is just two of the illegal wars.
The government kills many many more people than the death penalty ever has in the US/UK combined at any stage its been illegal, usually by way of accident. The government/lawyers/judges will ALWAYS make mistakes, but they are trying to get rid of the worst members of society, nothing more or less. They aren't intentionally killing innocent people nor deciding that a higher innocent kill count than guilty is an acceptable loss for their goal, unlike the two wars we've been involved in where we've deemed innocents being killed a completely acceptable risk. America the "death penalty" country has still killed a very small portion of the criminal population largely out of fear of killing potentially innocent people. But as always, its shocking for a state to kill people it believes to be murderers/rapists, infact its uncivilised, but if we're killing innocent people in other countries without really giving a damn, that's ok.
Someone who commits a robbery and shoots and kills people, is seen as a murderer, someone who stands up during a robbery trying to defend himself or others and kills the criminal, is seen as killing in self defence and is in no trouble. Someone who walks in midway through and kills the guy trying to defend others by accident believing him to be the criminal, is also not guilty, he tried to do the right thing but accidentally did the wrong thing. Its all about intent, our entire law system is based on it. The death penalty is TRYING to do the right thing but sometimes getting it wrong, the intention is fine. Going to war in Iraq was flat out wrong(for the reasons given) and the lack of care over who gets killed is absolutely wrong, the sheer number of innocent people killed is shocking beyond reason, but its fine because its not "our" people.
Some of those cases CRAZY listed are simply **** cases to start with, but for me, if I had the choice of being beaten and raped in jail for 50 years on a bad case, or even a decade, I wouldn't be the same person coming out if I was randomly found innocent at a later date. I would PREFER to die somewhat peacefully than live in fear, pain, and the complete control of violent horrific people for months, let alone years or decades.
A bad sentence against innocent people is an unavoidable circumstance with no end in sight, you're confusing wrongfully found guilty and the method of punishment. A genuinely innocent person will simply not be the man who comes out of a decade in jail if they are found innocent, killing them or leaving them to be brutalised in jail, both are horrifically awful outcomes, neither is better or worse, either way you kill the man that goes into jail, one way the innocent man has some relative peace, the other way another man comes out of jail after years or decades of often horrific treatment a completely different person anyway.
I'd choose to die, innocent and wrongly accused the person I am than a beaten, tortured person 10-20 years later unable to live normally anyway. Get rid of the death penalty in the states, innocent people are just going to end up in gen pop being treated much worse and having their lives completely destroyed, just in a different, much more violent, much worse way. The problem is the legal system and its focus, usually politically motivated, causing one person commiting a crime to get one punishment one month and a different punishment 3 months later when the same crime isn't as "popular" in the media. Likewise prosecutions choose who to prosecute, if in the publics eye someone is SEEN as being guilty and the crime is particular in focus in the media, prosecutions are more likely to push for a conviction on bad evidence than at another time when they might think getting a conviction helps no one.
When people's jobs are based on the publics opinion, and therefore who gets prosecuted and why is subject to people getting elected and looking as tough on a changing scale you're in trouble. None of that has anything to do with the death penalty.
