Brain Scans Used In Murder Sentencing

sciencehabit writes "For what may be the first time, fMRI scans of brain activity have been used as evidence in the sentencing phase of a murder trial. Defense lawyers for an Illinois man convicted of raping and killing a 10-year-old girl used the scans to argue that their client should be spared the death penalty because he has a brain disorder. Some experts say the scans are irrelevant because they were taken 20+ years after the crimes were committed. Others point out that the scans are only being considered because the sentencing phase of a trial has less stringent standards about evidence than those used to establish a defendant's innocence or guilt." In the Illinois case, the fMRI defense didn't help the defendant, whom a jury sentenced to death.

    If a suspect has already committed a crime that warrants life in prison without parole, then that suspect will have something to lose by committing more crimes.

    I could see that. Bank robbery goes wrong, accidentally kills someone, robber keeps killing because they've already crossed a line they didn't want to cross...

    Even if you're wrong, it certainly seems that capital punishment does little to reduce crimes we currently deem worthy of capital punishment.

    OK, so outlaw capital punishment. Then we have a new problem.

    Life imprisonment can encourage heinous crimes. If a suspect has already committed a crime that warrants life imprisonment, then that suspect will have nothing to lose by committing more crimes.

    See where this is going?

    I'm not in favor of capital punishment either, but your argument against it is specious.

    Incarceration is not for punishment or revenge; it serves 3 purposes to society:
    1) Deterrent
    2) Rehabilitation
    3) Preventing the criminal from re-offending, at least for the time period they are incarcerated.
    Of these, it can only be proven effective at accomplishing the 3rd purpose. People with a high probability of re-offending should be kept locked away indefinitely for the protection of others. Capital punishment is probably cheaper than keeping somebody in jail for the rest of their lives, but risking the execution of even 1 innocent person before they are exonerated is not a risk I'm willing to take. Finally, truly twisted criminals tend to not last very long in prison anyway; they are eventually given the Jeffery Dahlmer treatment where they are left alone with a lifer who hates them while the guards look the other way. Even cold blooded killers have no stomach for someone who rapes and kills little girls, and I probably wouldn't go out of my way to protect them from the rest of the prison population either.

    There are some specific cases where brain abnormality evidence seems like it would be very valuable to the defendant. This guy for instance. Initially pretty normal. Gradually develops increasingly problematic sexual misbehavior. Just before being sent to jail, goes to the ER with a headache and neurological symptoms. They MRI him and chop out a huge tumor pressing on his frontal lobe. Sexual misbehavior stops.

    Some time later, it starts up again. They check, and the tumor has partially regrown. Tumor is again resected, and patient is again fine.

    In a case like that, there seems to be a compelling argument to be made that the defendant's behavior is a medical problem rather than a criminal one(and a treatable medical problem, not an "well, enjoy the secure ward for the rest of your life" medical problem). If, though, your plea is basically "But, but, this MRI shows exactly the part of my brain that makes me a violent shitbag..." That seems fairly useless to you(though it might be helpful in the long term, if it helps us figure out how to stop producing people like you). Obviously, with sufficient scientific knowledge, it will be possible to identify the anatomic basis of your behavior. So what?

    There's one more point that just came to my mind, though it is, perhaps, somewhat U.S.-centric, and it may be my wrongful interpretation anyway as I'm not an American. If you start with the concept of inalienable rights, the famous "life, liberty, and the pursuit of happiness", then wouldn't any wrongful execution, being intentional deprivation of a person's life, violate his inalienable right? And therefore, unless you can guarantee with absolute certainty (meaning just that - 100% - not 99.9...%) that executions are never wrongful, death penalty as an institution is inherently in violation of the right to life?

    (Yes, I know that the phrase comes from the U.S. Declaration of Independence rather than Constitution, and therefore has no legal force. Nonetheless, if one subscribes to the notion of inalienable rights in the first place, they are inherently above laws.)

    You know, I always thought is was how a person was raised, and not their DNA, that made them who they were, that is, until it happened in my own family.

    My two cousins, lets call them Rick and Don, were raised exactly the same way, in fact until Rick turned 16 and everything came out we all thought they were biological brothers. It turned out my Aunt and Uncle had been told when they lived in Texas they couldn't have kids, and therefor adopted Rick at less than a week old, naturally boom a year later Don is born. They were very "all children are gifts from God" and spending many a night in their home and living down the street from them I can attest they never treated either kid differently from the other. But before Rick was even 12 there were problems-torturing animals, stealing, vicious behavior, bullying, etc. Finally they managed to get the court records unsealed and ....damn.

    It turned out Rick's mom was a whore who was doing 10-20 for cutting up a John over a fee with a razor, and his dad was her pimp who I swear was a fricking axe murderer! No shit, they guy got into an argument over cash, went to his truck, got an axe and chopped the guy into little pieces and got life without parole. Now Rick is locked up in the same prison where his biological dad died, charged as a habitual offender he most likely will never get out again. My aunt and uncle spent huge sums of money trying to help him, therapy, drugs, etc all to no avail. Don is about as boring as you can get, I don't think he or his wife have ever gotten so much as a traffic ticket.

    So I really have to wonder if there is something in the DNA. My aunt looked up his biological family and both sides were nothing but violence-rapes,beatings, killings, etc as far back as she could find.And as I said both boys were raised side by side, same house, food, treatment, etc, in a house filled with love and caring parents. So maybe there is something to the "bad gene" idea, who knows. Maybe we can isolate the genes and hopefully get rid of them. But watching it unfold in my own family killed the whole "it is just the environment they are raised in" BS for me. Because they got Rick straight from the hospital and he had never been exposed to his family, nor would he or any of us even known they existed if things hadn't gone so wrong.

    Is it, though? Now we're getting into the philosophy of punishment. There are three basic motivations that I can see for punishing someone for a crime (as distinct from forcing them to make reparations):
    • To reduce the likelihood of re-offending (especially applies to incarceration).
    • To serve as an example, to deter others from perpetrating the same offense
    • Revenge

    Imagine a kiddy fiddler of the worst order. He's molested scores of children, caused untold harm to them, etc. Now imagine that, on the day that he's caught, they can for whatever reason clinically prove that he's 'cured' and would be constitutionally unable to re-offend. Should he go free? I imagine the response would be a universal and emphatic "no, of course not!" The only motive for incarcerating or executing him at this point would be revenge.
