Which type of officer has jurisdiction only on property owned by their employer?

Company police officers are specifically appointed to provide security and enforce laws on property owned by their employer. Their jurisdiction is limited to that private or corporate property and does not extend beyond it. This means that they are authorized to act within the boundaries defined by the employer and can enforce company policies as well as certain laws that pertain directly to the property.

In contrast, sheriffs and city police officers have broader jurisdiction, typically covering large geographic areas such as counties or cities, and are responsible for enforcing laws across public areas, including highways, streets, and parks. ABC officers, who are primarily focused on enforcing alcohol laws and regulations, also operate within more extensive jurisdictions that are not limited to a specific employer's property. Thus, company police officers uniquely stand out because their authority is confined to the specific areas owned and managed by their employer.
