Comprehensive Detailed Explanation:

The " Theft Triangle " is a concept used in physical security and loss prevention to illustrate the three primary elements that must exist for theft to occur: motive, desire, and opportunity.

Motive: The reason someone considers committing theft (e.g., financial hardship).

Desire: The internal emotional or psychological urge to obtain something.

Opportunity: The circumstances or vulnerabilities that allow the act to occur.

All three must typically be present for theft to happen. This model is used in behavioral risk assessments and insider threat prevention strategies.
