I've watched small info releases and publication of work on this system and it's type over the last several years, but it's now moved into a Police Department near you and me--Now. From the article:

"According to a report from the Washington Post, when Fresno police received a 911 call about a man threatening his ex-girlfriend, they consulted the “Beware” software, which “scoured billions of data points, including arrest reports, property records, commercial databases, deep Web searches and the man’s social media postings.”

The software search found that the man had both a “firearm conviction” and a “gang association,” which put his “threat level” at the highest of three possible color-coded scores."
And:
"“It’s trying to forecast based on maybe your past behavior, or what is seen in your social media – a change in behavior or a change in the things you’re posting about,” Smith said. “They say ‘maybe this person is going to perpetrate a crime in the future,’ and then they want prevention from police officers.”"

I'd guess in 2yrs or less, we'll see legislation to enable a pre-crime intervention law and I'd bet we'll see it offered as justification on a Pre-Crime Police Killing "mistake".
