Polygraph Examination Service of the Philippine National Police (PNP) Crime Laboratory - Region 10

The study investigated the polygraph examination of the Philippine National Police (PNP) Crime Laboratory – Region 10. The study applied the descriptive method with the use of a questionnaire involving 50 respondents with different professions or fields of specialization, distinctively: Precinct Commanders; Criminal Investigators; Judges; Public Prosecutors; and Public Attorneys. The questionnaire was administered to the Precinct Commanders, Criminal Investigators, Judges, Public Prosecutors and Public Attorneys in Cagayan de Oro City for the effectiveness of the PNP Crime Laboratory polygraph examination service. The study found out that the polygraph examination result was not accepted as evidence in Court or proving capable in convicting a suspect. However, most of the respondents agreed that the polygraph examination is a big help in the police investigation. The researchers believed that the Court must stress the information that even if the polygraph result is not acceptable as evidence in a Court trial, it is still capable and helpful in identifying and eliminating suspects during an investigation. The researchers also deemed that coordination between policemen and polygraph examiners, posed a high possibility in achieving the goals of the Philippine National Police.
