(1) The purpose of this Chapter is to ensure a minimum level of integrity, proficiency, and competence among company police agencies and company police officers. To achieve this purpose, the General Assembly finds that a Company Police Program needs to be established. As part of the Company Police Program, the Attorney General is given the authority to certify an agency as a company police agency and to commission an individual as a company police officer.

(2) A hospital, a State institution, or a corporation engaged in providing on-site police security personnel services for persons or property may apply to the Attorney General to be certified as a company police agency. A company police agency may apply to the Attorney General to commission an individual designated by the agency to act as a company police officer for the agency.
