We know that 90% of crime guns can be traced back to just 5% of gun dealers.
But since 2003, the Tiahrt Amendment, passed at the behest of the gun lobby, has limited the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) from publicly disclosing crime gun trace information. Over time, the Tiahrt Amendment has been interpreted to shield the most negligent gun dealers from public scrutiny while also depriving the public of key data to help stem the flow of illegal guns.
That's why our Combating Crime Guns program has used Freedom of Information Act (FOIA) requests and state and local gun tracing information to uncover trends in crime gun trace data.
In 2023, we released the most important gun trace dataset the public had seen in decades, examining trends in crime gun trace data secured in Pennsylvania. In 2024, we took this a step further, securing data on the top crime gun dealers in all of the U.S. This data is the clearest look we’ve had in two decades as to which gun dealers sell the most crime guns.
