Software Used To Predict Who Might Kill

eldavojohn writes "Richard Berk, a University of Pennsylvania criminologist, has worked with authorities to develop a software tool that predicts who will commit homicide. I could not find any papers published on this topic by Berk, nor any site stating what specific Bayesian / decision tree algorithm / neural net is being implemented." From the article: "The tool works by plugging 30 to 40 variables into a computerized checklist, which in turn produces a score associated with future lethality. 'You can imagine the indicators that might incline someone toward violence: youth; having committed a serious crime at an early age; being a man rather than a woman, and so on. Each, by itself, probably isn't going to make a person pull the trigger. But put them all together and you've got a perfect storm of forces for violence,' Berk said. Asked which, if any, indicators stood out as reliable predicators of homicide, Berk pointed to one in particular: youthful exposure to violence." The software is to enter clinical trials next spring in the Philadelphia probation department. Its intent is to serve as a kind of triage: to let probation caseworkers concentrate most of their effort on the former offenders most likely to be most dangerous.

    Yeah, I think if you ask for it to answer that question, the algorithm responds "I'm sorry dave, I'm afraid I can't do that."

  4. Gun Ownership by Anonymous Coward · · Score: 1, Funny

    Why spend money to find-out what we already know? It's gun owners that commit nearly 100% of the murders in this country. If we put all of them in prison then we will all be safer. Unfortunately because many of those violent thugs have money and influence through the NRA we will never see a common sense approach to murder prevention. I will never understand why anyone other than a complete idiot would ever own one of those things given that it is 43 times more likely that you will kill yourself or a loved one with a firearm than kill in self-defense.

    Hopefully with the much better congress we have now we'll finally get real laws to protect us like we had with the assault weapon ban that was passed by the last good congress that has saved thousands of lives. Many of us are still here only because of the good work the last good congress did.

    has worked with authorities to develop a software tool that predicts who will commit homicide.

    Don't forget the best practices for committing a homicide:

    1. Commit often and early, to prevent victim escape.

    2. Copycat homicide is cheap, so don't be afraid to branch existing homicides, if you feel you need to.

    3. While committing a homicide, always write down a full log of what happened, and put it with it with body (or bodies). This won't just help the cops get oriented, but also to yourself when you come back to the crime scene, say, an year later.
