The group Everytown for Gun Safety used court records to trace more than 250 guns bought at nearly two dozen Academy Sports + Outdoors chain stores that had been trafficked over three years in a handful of federal straw purchasing prosecutions. The guns moved along familiar trafficking routes north to cities and states with some of the strictest firearms laws. Advocates say the cases highlights some of the red flags that licensed firearms dealers can ignore or miss as thousands of guns make their way to the hands of people otherwise prohibited from buying them. Academy Sports has not been accused by federal regulators of wrongdoing, and the guns trafficked north are a tiny slice of its overall sales.
