DARPA Conference to Discuss ‘Pre-Crime’ System — The Defense Advanced Research Projects Agency is trying to develop a system that would use powerful analytical tools to determine if a soldier is becoming homicidal or suicidal, or if an intelligence operator is about to turn double agent. Next week, DARPA will be holding a conference in Arlington to educate contractors about the development process for such a system. The publication Government Computer News compares such a system to the “pre-crime” technology in the Tom Cruise film “Minority Report.”
