The main purpose of this legislation is to enhance security measures against the threats posed by ghost guns, which are firearms that can be assembled at home and often lack serial numbers, making them difficult to trace. The legislation aims to improve the Department of Homeland Security's (DHS) ability to prevent, prepare for, and respond to potential acts of violence or terrorism involving these weapons. Key provisions of the legislation require the Secretary of Homeland Security to develop a comprehensive strategy within one year of the law's enactment.
