Predictive Policing For LE?

Software predicts violent crime: Orange County Sheriff's Office using it to get results on crime

This type of technology is becoming more popular for Law Enforcement. Any thoughts on it?

I have to assume this has always been a key strategy to policing. But if software can help you make a more accurate assessment of your problem areas, or even just free up man-hours to do other tasks besides analyzing crime statistics, then I'd count it as a win.
