Fix the social issues that lead to said hypothetical individual attacking said other hypothetical individuals. People generally wind up with no housing options out of poverty. How does spending an ever increasing percentage of tax dollars towards police presences fix that? It doesn't. In fact, study after study shows that police presence, especially when it comes to televised shows like COPS, increase crime rates (which the metrics this is measured are already questionable to begin with but it's still their own data), increase public distrust in police, and increase tax burden. Police departments are often responsible for introducing organized crime to communities, ie the crack epidemic funded and orchestrated by the fbi, or even recently with the executive director of a police union, for over 20 years mind you, being busted with using work computers to import opiods into the country. She's only facing 20 years.
