Gun Trace Report
Since 2013, the Chicago Police Department has recovered nearly 7,000 “crime guns” each year. For the purposes of this report, a crime gun refers to a firearm recovered by CPD that was illegally possessed, used, or suspected to be used in furtherance of a crime.
The overwhelming majority of these firearms were originally purchased outside of the city limits and brought into Chicago. So far in 2017, CPD is already on pace to exceed last year’s gun recoveries. It is self-evident that the availability of illegally circulated firearms in Chicago is directly connected to its deadly street violence. Simply put, each conflict becomes potentially more lethal due to easy access to a gun.
In an unfortunate but persistent reality, certain retailers and jurisdictions disproportionately account for the guns trafficked into Chicago that sustain its illegal gun market and associated violent crime.
