Stolen guns, untraceable weapons and other deadly devices are becoming more prevalent in U.S. gun crimes, new federal data shows.

Last week, the Bureau of Alcohol, Tobacco, Firearms and Explosives released an expansive federal report on guns used in crimes in two decades, providing the public with more detail about stolen firearms and gun trafficking.

The data stretches from 2017 and 2021. During that period, local police reported a shrinking turnaround time for a legally purchased gun to be used in a crime. It also provides insight into the spike in ghost guns and conversion devices.ATF Director Steven M. Dettelbach wrote that the findings offer “strategic intelligence” for policymakers, law enforcement and researchers to reduce gun violence.
