Quote from article:

"Neither the ATF nor Minneapolis police can quantify the number of crime guns that have originated from gun shows. However, Minneapolis Deputy Police Chief Rob Allen estimates they make up just a small portion of guns recovered in Minneapolis. Instead, Allen said, the bulk of guns used in crimes are stolen from lawful gun owners. "
