Which of the following is NOT considered a security measure in crime prevention programs?

Operation identification is a process where individuals mark their property with identifiable information, typically to deter theft and assist in recovery if stolen. While it plays a role in crime prevention by helping individuals take proactive steps to protect their belongings, it is not a physical security measure like alarm systems or direct community actions like neighborhood watch or community patrols. The other options—alarm systems, community patrols, and neighborhood watch—are actively involved in preventing crime through immediate response or surveillance, making them more traditional security measures within crime prevention programs. Therefore, operation identification stands apart as a less direct method of security compared to the others listed.
