The main purpose of this legislation is to enhance the ability of victims of gun violence to seek justice in civil courts. It aims to repeal existing protections that shield gun manufacturers and sellers from lawsuits related to gun violence, thereby allowing victims to use gun trace information as evidence in their cases. Key provisions of this legislation include the repeal of specific sections of the Protection of Lawful Commerce in Arms Act, which currently provides immunity to gun manufacturers and dealers from being sued for crimes committed with their firearms.
