> Many police still perform patrols around the city, and the data does not support the efficacy of that. There's a lot of value in having patrols even in low crime areas. It means that when something does go horribly wrong, or even when residents just need help, that help isn't terribly far away. It also prevents "police free zones" which criminals would quickly discover and be happy to exploit. That said, police certainly should be patrolling areas where crime is more prevalent more frequently.
