There are a wealth of proposals. For example https://www.lib.uchicago.edu/collex/exhibits/letters-prison/prison-abolition/ https://www.lib.uchicago.edu/collex/exhibits/letters-prison/... which links to on-going projects. Many begin with the questions of what are prisons for? What is policing for? What are the problems these approaches are trying to solve? What percent of violent crimes are committed by people in dire mental and financial stress? Can we resolve those issues by creating communities that address their needs and difficulties? It starts by asking questions about the ways violence and "crime" happens. Maybe there are people where you are that are actively addressing the question.
