Senator Raffy Tulfo on Friday filed a resolution urging the Senate to probe alleged abuse, killings and human rights violations by the members of the Philippine National Police due to their "persistent failure" to follow police operational procedures.

Senate Resolution 767 is urging an appropriate committee in the upper chamber to undertake an inquiry against police officers engaged in abuse of power, criminal acts and violation of human rights.

Tulfo lamented that cops must enforce the law accordingly, maintain peace and order, and ensure public safety and internal security in the country. However, he lashed out about several reports indicating that police operations have failed due to their negligence in operational procedures.

He cited the 12 August incident wherein Pandi police officers entered the property of Rodelio Vicente claiming they were just conducting a "manhunt" for an alias "Elmer" without any warrant of arrest or justification.

The cops eventually arrested Vicente for allegedly committing direct assault and disobedience to a person in authority and was taken into custody for no valid reason.

Tulfo slammed the arresting cops for not wearing their uniforms and using ski masks during the supposed manhunt operations. Vicente's daughter was also physically assaulted by these police officers.

Also, Tulfo cited the case of John Francis Ompad who was killed by Police Corporal Arnulfo Sabillo from the PNP Rodriguez, Rizal last 20 August while conducting an "Oplan Sita" — a police checkpoint.

Ompad allegedly refused to show driving documents and ran away from the checkpoint, prompting Sabillo to chase the rider and shoot him.

"The aforementioned two incidents happened within the same month; and just weeks after the death of Jerhode Jemboy Baltazar who was killed by PNP Police Operatives from Navotas under a claim of mistaken identity," Tulfo wrote in his resolution.

"The operation was found to have had several irregularities and non-compliance with the PNP Police Operations Procedure," he added.

Tulfo stressed that the protection of human rights remains a "fundamental principle" enshrined in the Constitution.

He further pressed the need for the police officers to strictly observe their Police Operations Procedure and to ensure strict application of the internal discipline of the PNP.
