Chicago Police Department Goes High-Tech to Fight Rise in Killings

The last year has been rough in Chicago:

As the number of Chicago's homicides rose 58 percent in 2016, to 764, the clearance rate — killings that ended in an arrest — dropped from 36 percent to 26 percent, according to an analysis by the University of Chicago's Crime Lab.

The city is still leaning on technology to help fight crime, from NBCnews:

The steps announced Friday included:

  • An expansion of ShotSpotter sensors that pick up the sound of gunfire and alert police to its location.
  • Near-ubiquitous coverage of public areas by surveillance cameras.
  • The introduction of predictive policing software that identifies areas most likely to see gun violence.
  • Layering that analysis with another predictive program that identifies people most likely to commit —or be the victims of — gun violence.
  • A "war room"-like office, staffed with analysts who will translate that data for changes to deployments and long-term strategy.
