Software to predict violent criminality

This really pisses me off. We will continue to waste time on statistical analysis to predict criminality. When will we learn that people are extremely unpredictable creatures. No one's cognitive processes work the same way. Likeliness is not good enough to lock someone up, or force them to get help.

Ahh, but what if it does work? Who knows what the government has been keeping on us about probability of stuff.

Criminal profiles (a psychological profile usually formed while searching for a criminal of a certain crime, that is) are generally quite accurate because there are certain personality attributes that most (but not all) killers have in common. But then, I've always believed everyone is capable of killing, it just depends on their personal situation and mindsets at that particular moment.

I don't think it will be a successful system, overall. I mean, if you look at...any random well-known serial killer in the past, they're often the types of people you'd never expect to be capable of shoplifting, much less killing over 100 people. I don't really have a problem with increased security on high-risk probationers, so long as it doesn't decrease the security on lower-risk probationers. 'Cause you know that's bound to happen, they watch the wrong fellow and the other guy goes off and kills.
