The main purpose of the Strengthen and Tackle Opportunities to Prevent Violence Act of 2025, also known as the STOP Violence Act of 2025, is to enhance safety measures against mass violence in public spaces. This legislation aims to provide additional financial support to states, local governments, and nonprofit organizations that work to protect communities from incidents of mass violence, such as active shooter situations. One of the key provisions of this act is the allocation of $20 million in grants from the Attorney General.
