Which of the following does NOT qualify as a peace officer under Texas law?

Under Texas law, a peace officer is defined as a person who is elected, appointed, or employed to enforce the laws of the state or laws enacted by municipal or county governments. City police officers, county sheriffs, and state rangers all fall under this category as they are individuals who have been granted the authority to uphold the law and maintain public safety.

In contrast, private security guards do not have the same legal authority as peace officers. They are typically employed by private companies to protect specific properties or businesses and do not possess the same powers of arrest or law enforcement as peace officers. Their responsibilities are more oriented towards security rather than law enforcement, which is why this option does not qualify as a peace officer under Texas law.
