What is a program in which neighbors work together to help reduce criminal opportunity?

The most suitable answer is a block watch, which is a community program that encourages neighbors to collaborate in observing and reporting suspicious activity to local law enforcement. The primary goal of a block watch is to enhance neighborhood security by fostering a sense of community where residents look out for each other. This proactive approach helps deter crime by increasing the visibility of residents and building a network of communication that facilitates the quick relay of information to authorities.

This program typically involves regular meetings where residents can discuss safety concerns, share experiences, and develop strategies for vigilance against crime. Engaging the community in such a proactive manner empowers residents to take an active role in their safety, creating a safer environment overall. Programs like block parties or other neighborhood gatherings may help build community spirit but do not directly focus on reducing criminal opportunity as comprehensively as a block watch does.
