HB1373 expands firearms tracing in the United States by directing Illinois law enforcement to use the National Tracing Center's (NTC) eTrace platform. The Senate passed HB1373 on May 31, 2025, by a vote of 43 to 11. We have assigned pluses to the nays because eTrace is the firearm tracing system of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), an unconstitutional federal agency within the U.S. Department of Justice (see U.S. Const., Art. I, Sec. 8). The federal government has no authority to engage in this activity, as made clear by the 10th Amendment. Further, Illinois' participation in the eTrace "collective data sharing program" enables state and local governments to conduct mass surveillance, contribute to the creation of a national gun-owner database, and/or confiscate firearms from law-abiding citizens, in violation of the 2nd, 4th, and 5th Amendments. The systematic tracking of firearms must be stopped at all levels to prevent the enforcement of gun-control laws.
