DECEPTION DETECTION TESTS IN CRIMINAL INVESTIGATION WITH SPECIAL EMPHASIS ON NARCO ANALYSIS: EXAMINING THE LEGAL POSITION IN INDIA

Abstract

There are several methods for Criminal Investigation. Scientific techniques like polygraph, narco-analysis, etc., are becoming common in the present time for crime detection. These scientific techniques have proved to be a boon in criminal investigation. Narco-analysis has become increasingly common and famous in India among criminal investigating agencies. However, these scientific techniques are also challenged and criticised as being violative of our constitutional ethos. The current paper attempts to examine issues concerning the scientific techniques of criminal investigation, and the author has focused specifically on the narco-analysis method of criminal investigation and will examine the evidentiary value of the narco-analysis test.

Key Words: Criminal Investigation, Narco-analysis, Scientific Techniques, Constitutional Ethos.
