Which of the following groups is NOT considered a peace officer?

Private security guards are not considered peace officers because they do not possess the same legal authority as sworn law enforcement officials. Peace officers are typically government employees, such as police officers or deputies, who have the authority to enforce laws, make arrests, and carry firearms as part of their official duties.

While private security guards may have duties related to maintaining safety and security within their assigned areas, their powers are generally limited to the scope of their employment and do not extend to the authority granted to peace officers. Consequently, they do not carry out law enforcement activities in the same formal and authorized capacity.

In contrast, airport police officers, investigators for the Texas Racing Commission, and marshals of incorporated cities all serve in official capacities that grant them powers associated with law enforcement, thereby qualifying them as peace officers.
