Polygraph to aid investigators

… CID Boss calls for law to be instituted

 The Director-General of the Criminal Investigation Department (CID), DCOP/Mrs Maame Yaa Tiwaa Addo-Danquah said, the use of the polygraph would go a long way to help investigators in identifying criminals who mislead them in investigations.

In an interview at the end of the maiden integrity management breakfast forum, Addo-Danquah said “I would go for it if the law allows us to use polygraph.”

A key component of the investigation process is the adoption of technology to provide a scientific validity. Research also has proven that polygraph testing is a globally acceptable approach towards clearing doubts during investigations.

Former President Jerry John Rawlings has also called for such technologies to be used in African courts, which is to ensure that the truth is always established.

The Director-General said, “some people are such that even when they are telling lies, you are not able to identify and differentiate between what they are saying are lies or not.”

“So for investigative purpose, it gives you an assurance that what this person is saying maybe true or not,” she added.

The American Polygraph Association (APA) is of the view that scientific evidence supports the validity of polygraph examinations that are conducted and interpreted in compliance with documented and validated procedure.  Thus, such polygraph examinations have great probative value and utility for a range of uses, including criminal investigations, offender management, and selection of applicants for positions requiring public trust.
