When a duty is assigned to a sheriff by the code of criminal procedure, who else can perform that duty?

The correct choice highlights that any deputy has the authority to perform duties assigned to a sheriff under the code of criminal procedure. This flexibility is essential for the efficient functioning of law enforcement agencies, as it allows for a delegation of duties and responsibilities to trained personnel. Deputies are sworn officers who have received the necessary training and are authorized to act on behalf of the sheriff in carrying out law enforcement tasks.

This system ensures that the sheriff's office can effectively respond to various situations, even when the sheriff is unavailable. The inclusion of deputies in performing these duties helps maintain the continuity of law enforcement operations and supports the overall safety and security of the community.

While the other choices suggest alternatives, they do not align with the established legal framework. A personal assistant or a volunteer lacks the formal authority and training required to perform law enforcement duties. Similarly, while a chief deputy may play a significant role in the organizational structure, the code specifies that any deputy—regardless of rank—can carry out the sheriff’s assigned tasks. Thus, the broad empowerment of deputies is crucial for operational efficiency and responsiveness in law enforcement.
