DELHI: Today, the court gave permission to Delhi Police to conduct a polygraph test on Aaftab Amin. He is the main accused of Shraddha Walkar Murder Case. Yesterday, the Delhi Police has moved its application for the same.
A polygraph test is a non-invasive technique in which no medicine is used. The subject is attached to a machine and questions are asked to him/her about the matter related to any case or incident. The variation in the graph when the subject answers the questions are mapped to draw a conclusion.
According to the American Psychological Association (APA), polygraph tests measure a person’s “heart rate/blood pressure, respiration, and skin conductivity”. The purpose of the test is usually to prove whether or not a person committed a crime.
