Government Accountability Institute President Peter Schweizer says China has been targeting gangs and felons in the U.S. with advertisements for Glock switches, a small, metal device made in China that turns a Glock handgun into a fully automatic machine gun. “They were specifically trying to get these into the hands of groups that want to sow chaos and violence in the United States,” says Schweizer. “As a result of this, between 2018 and the present the rate of machine gun fire in American streets has skyrocketed by some 5000%.”
