Minneapolis Domestic Violence Experiment studied the deterrent effect of various methods of handling domestic violence.

• A. Neighborhood Watch
• B. Minneapolis Domestic Violence Experiment
• C. Operation Identification
• D. Police Athletic Leagues

Answer: (B)

The key idea is assessing whether how police respond to domestic violence can deter future incidents. The Minneapolis Domestic Violence Experiment is the study that actually tested this by randomly assigning cases to different handling strategies (such as arrest, separation, mediation, or counseling) and measuring subsequent violence. The other options refer to programs with different goals—Neighborhood Watch is about community crime surveillance, Operation Identification focuses on property marking for theft deterrence, and Police Athletic League is a youth outreach program—so they don’t examine police responses to domestic violence. This makes the Minneapolis Domestic Violence Experiment the correct choice because it directly investigates deterrence through policing methods.
