This study was anchored on the idea of implementing the My Brother’s Keeper Squad system in the Philippine National Police as an Internal Cleansing Strategy that aims to prevent police abuses and to identify and weed out defiant PNP personnel, particularly those who are engaged in illegal activities, and impose corrective and punitive measures. It also aims to instill in all PNP personnel a strong sense of commitment, dedication, and responsibility to police work geared towards a Godcentered, service oriented and family-based life. This study attempted to know the effects of implementing the My Brother’s Keeper squad system to the PNP Personnel of the Hagonoy Municipal Police Station as a corrective strategy for erring PNP personnel. The study adopted an action research and also used descriptive qualitative research designs to picture the effects and challenges of the PNP Personnel in the implementation of such internal cleansing strategy of the PNP. Upon the analysis of this study, there are two themes developed in the implementation of My Brother’s Keeper squad system in the Philippine National Police: (1) God-centered; and (2) Service-Oriented. The result of the study implied a clear indication that the Squad system emphasizes values formation, spiritual development and strengthening its commitment of its personnel to their profession, however, for every system implemented, it also have challenges to face on. This study also identified some challenges to improve: there are no sufficient time to internalize, no proper venue to conduct the session and hesitations to share that may lead to misunderstanding or conflict of belief/faith.
