What are the four Ds of prevention?

• A. Detain, Depose, Disable, Describe
• B. Deter, Deny, Delay, Detect
• C. Delay, Detour, Divert, Detect
• D. Deflect, Deny, Destroy, Discover

Answer: (B)

The idea here is a practical framework for reducing crime opportunities by shaping what a potential offender encounters. The four Ds are Deter, Deny, Delay, and Detect. Deter means making crime unattractive by increasing the perceived risk and effort, through things like visible security measures, lighting, cameras, and patrol presence. Deny means remove access or opportunities so there’s nothing to take or no way to act—think locks, controlled entry, secure storage. Delay means slowing someone down so they have less chance of succeeding and responders have time to intervene—strong doors, reinforced frames, time-delay mechanisms. Detect means providing early warning and rapid response capabilities—alarms, sensors, cameras, and monitoring that help catch incidents quickly. Other option wordings don’t fit this preventive framework because they describe actions like detaining, destroying, or diverting, which aren’t part of the standard four-step prevention approach. The established set is deter, deny, delay, and detect.
