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

The correct answer is "block watch" because this program specifically involves a group of neighbors who collaborate to enhance the safety of their community by monitoring each other's homes and reporting suspicious activities to law enforcement. The concept behind a block watch is to foster communication among residents, increase alertness, and create a sense of community pride, which collectively plays a crucial role in deterring criminal activities.

In a block watch program, residents typically engage in regular meetings, share information about crime trends or safety concerns, and participate in neighborhood patrols. The sharing of ideas and strategies helps empower community members and creates a more vigilant environment, ultimately reducing the opportunities for crime.

Other options, such as a block party, focus primarily on social engagement rather than crime prevention. Operation neighbors and community watch might suggest similar concepts, but they do not specifically denote a structured approach like a block watch, which historically has been recognized for its effectiveness in crime reduction through neighborly cooperation.
