Which act created the National Police Commission with the power to supervise and control police forces in the country?

The creation of the National Police Commission, along with its power to supervise and control police forces in the country, is established by Republic Act 4864. This act was pivotal in the administration of police services, aiming to improve overall police organization and efficiency. It sought to enhance police accountability, oversight, and the operational standards of law enforcement agencies. The establishment of the National Police Commission under this act marked a significant step towards creating a structured and regulated police system designed to better serve and protect communities.

In contrast, the other acts listed, while related to law enforcement and public safety, pertain to different aspects and developments within the framework of police functions and administration. For example, Republic Act 6975 focuses on the creation of the Department of the Interior and Local Government and the integration of a national police force, while Republic Act 8551 subsequently amended certain provisions to further establish police reforms. Nonetheless, it is Republic Act 4864 that specifically addressed the need for direct supervision and control through the formation of the National Police Commission.
