“That’s a significant reduction. It’s not where we want to be, of course, but it is showing signs of progress,” Police Supt. Eddie Johnson said.

Police said burglaries, robberies, and car thefts also are at a 20-year low.

Johnson said violent crime has been going down in Chicago for the past three years, and pointed to the creation of new “strategic decision support centers,” which the department began installing in district stations in 2017. The so-called “nerve centers” are equipped with ShotSpotter gunshot detection systems and other high-tech crime-fighting tools.

“Since we initiated the strategic decision support centers in 2017, we’re down about 50 percent in terms of gun violence overall,” Johnson said.
