Final answer:
The National Sheriffs' Association launched the Neighborhood Watch program, fostering cooperation between residents and law enforcement to improve community safety.
Step-by-step explanation:
The national organization responsible for launching Neighborhood Watch is the National Sheriffs' Association (NSA). This program was developed to facilitate cooperation between community members and law enforcement to monitor and report suspicious activities, ultimately enhancing neighborhood security.
The Neighborhood Watch program empowers residents to take an active role in protecting their own communities through vigilance and communication, similar to how they might collaborate to maintain property values by taking care of common areas and advocating for local amenities.
