The testimony on small arms points out the way the United States government regulates the export of small arms. The State Department and the Commerce Department both have a hand in overseeing the export of arms. The Trump administration changed the jurisdictions that each department and expanding the types of weapons the Commerce Department oversees.
Outlook: This change in policy is concerning to many. The exported weapons regulated by the Commerce Department do not have to be made known to Congress and there are less controls in place to limit the risk of arms falling into the wrong hands. It is thought that if the current administration’s policy goes into full affect then more semi-automatic weapons and other weapons once considered to be military grade will be more likely to fall into the hands of terrorists, drug traffickers and other criminals.
