theodp writes "Remember the Pre-Cogs in Minority Report? Slate's Will Oremus does, and wonders if Google could similarly help the police apprehend criminals based on foreknowledge collected from searches. Oremus writes: 'At around 3:45 a.m. on March 24, someone in Fort Lauderdale, Fla., used a mobile phone to Google "chemicals to passout a person." Then the person searched Ask.com for "making people faint." Then Google again, for "ways to kill people in their sleep," "how to suffocate someone," and "how to poison someone." The phone belonged to 23-year-old Nicole Okrzesik. Later that morning, police allege, she and her boyfriend strangled 19-year-old Juliana Mensch as she slept on the floor of their apartment.' In theory, Oremus muses, Google or Ask.com could have flagged Okrzesik's search queries as suspicious and dispatched cops to the scene before Mensch's assailants had the chance to do her in." I bet you're already thinking of just a few reasons why this might not such a good idea.
