Predictive policing. With violence on the rise, Chicago has turned to big data to predict gun and gang violence.

Chicago’s murder rate – with gun deaths at the fore – is soaring again. Off the charts. Up another 50 percent from last year this time, and last year was already bad. Chicago police are desperate for an answer. What they’ve been trying is called “predictive policing.” Just 1,400 Chicagoans out of nearly three million are responsible for most of the violence. So, fire up an algorithm and predict who will murder. Who will be murdered. And try to stop it. This hour On Point, predictive policing in Chicago.

From Tom’s Reading List

The Marshall Project: The ‘Chicago Model’ of Policing Hasn’t Saved Chicago — "Local rappers have branded the city Chi-raq. It’s no stretch. Chicago’s 2015 citywide homicide rate was 17 per 100,000 residents, compared with a national rate of four. In Chicago’s 11th police district the rate is 62. (Iraq’s rate is 20.)"

Los Angeles Times: Nearly 1,400 people shot this year as Chicago braces for summer violence -- "The number of people shot in Chicago is running 50% above the figure from this time last year as the city braces for the summer, traditionally its most violent period. So far this year, at least 1,382 people have been shot in Chicago, and at least 244 of them have died of their wounds. Last year at this time, 904 people had been shot, 157 of them fatally."

FiveThirtyEight: We Now Have Algorithms To Predict Police Misconduct — "Many police departments have early warning systems — software that tracks each officer’s performance and aims to forecast potential problems. The systems identify officers with troubling patterns of behavior, allowing superiors to monitor these cops more closely or intervene and send them to counseling."
