I think Jiro is getting hammered by all the ladies today,
I think we should keep the death penalty for premeditated murder, someone looking to out right kill someone else for personal gain. And for it to be effective the punishment would have to be carried out within 6 months of sentencing. As it stands right now, we have inmates that have been on death row for 20+ years and they are allowed to go outside in the exercise pen, and they get free cable in their cells plus 3 meals a day. Knowing that even if you were sentenced to death, you would likely still get another 5-20 years to live isn't much of a deterrent. You can still run a business, keep in contact with your family and what not all from the inside of your cell, you just have to do it via snail mail. While your sitting in jail running a buisness your kid and wife (or hubby) could be living it up outside your cell, not because they're swindling the income, but because you direct what needs to happen, and any extra money gets sent home.
I know this sounds like ridiculous emotional thinking(and maybe part of it is), but knowing that if you planned out a murder and got caught, and there was a chance you'd have just 6 months to live with a guilty conviction, you'd probably think that's too high of risk.
But I also understand why we have inmates sitting on deathrow for so long, its so that those who are wrongly convicted and are actually innocent can have an appeal to a higher court (and numerous innocent deathrow inmates have been set free by modern DNA testing that proved they were not the murderer). Six months is a short amount of time, maybe too short given how backlogged our entire system is. It would take years for us to get caught up on every single case.
But another part of me understands the 'crime of passion' where a jealous husband murders his wife's lover, or even his wife. Its the 'if-I-can't-have-them-nobody-can-have-them' sort of mentality. They really aren't thinking of punishment. They are just thinking of how the murder would solve the problem for them. These people aren't thinking correctly to begin with, they are just furious, emotional, and these are the ones that need life in prison with no possibility of parole.
And there also those women who get beat by their husbands and out of frustration, just decide to shoot their husband while he's sleeping. Would the death penalty justify them? Did the motive justify the murder? Do these women eve deserve any kind of prison time? Some get prison time, some don't it just depends on the judge presiding over the case I think, and whether or not the jury is sympathetic towards the wife.
The more we get into this, murkier it gets. Our legal system is very complicated, and even in this system, there are always exceptions to the rule.
