The main purpose of the SMART Community Policing Act is to enhance community policing efforts by providing funding for innovative approaches to address mental health crises and improve community safety. The legislation aims to create better outcomes for individuals in crisis, particularly those dealing with mental health issues, poverty, homelessness, or substance use disorders, by fostering collaboration between law enforcement and mental health professionals. Key provisions of the Act include expanding the uses of existing funding under the Omnibus Crime Control and Safe Streets Act.
