Texas Security Guard License Practice Exam

Under what circumstances can a security guard detain a person?

1. If they witnessed a crime being committed and have reasonable belief that it is necessary

2. If they are unsure about someone’s actions

3. If they have received complaints about that person

4. If they suspect someone is trespassing

The correct answer is: If they witnessed a crime being committed and have reasonable belief that it is necessary

A security guard is authorized to detain a person under specific conditions dictated by Texas law. The primary circumstance is when the guard has personally witnessed a crime being committed and has a reasonable belief that detaining the individual is necessary. This authority aligns with the concept of "citizen's arrest," where private citizens—including security personnel—are allowed to detain someone they believe has committed a crime, provided they have directly observed the act. This legal provision serves to ensure the immediate protection of property and public safety. Being unsure about someone’s actions does not provide a sufficient legal basis for detention, as the criteria require direct observation of a criminal act. Similarly, receiving complaints about a person does not grant the authority to detain unless there is evidence of a crime being committed. Suspecting someone of trespassing might warrant observation and a report to law enforcement, but it is not enough to justify a detention without witnessed criminal behavior. Thus, the correct answer highlights the necessity of direct observation and reasonable belief in the commission of a crime as the key factors enabling a security guard to lawfully detain an individual.
