Human rights are very active in the PH, and cops were also afraid to be in the limelight of that controversy, especially now that every moment can be captured and uploaded on social media. I have 2 siblings who are an active member of the force and they told me that they are not even allowed to use mobile phones while on duty, or else the admin case is waiting.
Corrupt officials will always be present, it's not 100% clean... I am not saying we allow abuse, but we tried not to argue on the point of an officer killing a regular citizen.
