The "Invest to Protect Act of 2025" establishes a new grant program within the Office of Community Oriented Policing Services (COPS) of the Department of Justice. This program is designed to assist eligible local governments and Tribal governments that employ fewer than 175 law enforcement officers. Its primary objectives are to provide essential training and access to mental health resources for officers, alongside initiatives aimed at improving the recruitment and retention of local law enforcement personnel. The Director of the Office is mandated to award these grants within 120 days of the Act's enactment, utilizing a streamlined application process. Grant funds can be used for a wide array of activities, including de-escalation training , victim-centered training for domestic violence situations, and evidence-based safety training for various scenarios like active shooters or responding to calls involving vulnerable populations. The program also supports officer recruitment and retention through signing bonuses, retention bonuses (up to 20% of salary for officers with 5+ years of service who commit to 3 more years), and stipends for graduate education in mental health or social work. Additionally, it provides access to patient-centered behavioral health services for officers and funds data collection for police practices. The bill includes robust accountability measures, such as reporting requirements, public disclosure of bonuses, and audits by the Inspector General to prevent waste, fraud, and abuse, authorizing $50,000,000 annually for fiscal years 2027 through 2031.
