Which of the following is NOT classified as a peace officer?

In the context of law enforcement, a peace officer is generally defined as a person who is authorized to enforce the law, maintain public order, and ensure the safety of individuals and property. These positions usually include sworn police officers, sheriffs, and certain designated individuals such as district attorneys in their law enforcement capacity.

Private security guards, however, do not fall under the category of peace officers. They are employed by private entities to protect property and ensure the safety of individuals within their jurisdiction, but their authority is limited to what is granted by their employer and does not extend to law enforcement duties. Unlike peace officers, private security guards lack the official authority to arrest or execute warrants, which establishes their distinction from sworn law enforcement personnel.

In contrast, police officers, district attorneys, and city attorneys possess various degrees of formal authority and responsibilities aligned with law enforcement and public safety, solidifying their classification as peace officers in contrast to private security guards.
