There was a recent article over at the website Government Technology that looked at the future for predictive policing. In the piece, several prominent International Association of Crime Analysts members were quoted on their opinions on where predictive policing was headed.
Analysts currently identify crime trends using statistical data on arrests and 911 calls. Based on that information, police commanders deploy officers to areas they believe will be hot spots for illegal activities. But while predictive in nature, the effort is largely reactionary based on past events.
In the future, behavioral data and clues from virtual interactions may help cops stop bad guys before they’ve even drawn up a plan. Think Minority Report — the 2002 film where a police unit was able to arrest murderers before they committed a crime — on a more realistic scale.
It's a long piece but if your interested in where predictive policing technology might be going, you might want to give it a look.
