Sanjay Roy Polygraph Test: Unraveling the Kolkata Rape-Murder Case

The Kolkata rape-murder case has sent shockwaves across the nation. Sanjay Roy, the prime suspect in the heinous crime, is scheduled to undergo a polygraph test as part of the ongoing investigation. This development has raised questions and sparked debates about the reliability and implications of lie-detection tests.

Background of the Case

In September 2022, a 16-year-old girl was found dead in the Kolkata residence of the Late Ashok Kumar Minocha, a businessman and close associate of former West Bengal Minister Partha Chatterjee. The victim's body bore multiple injuries and signs of sexual assault.

Initial investigations led to the arrest of Sanjay Roy, an employee of Minocha. Roy initially denied involvement but later confessed to the crime in police custody. However, during a court hearing, Roy retracted his confession and pleaded not guilty.

Polygraph Test Announcement

In an effort to corroborate Roy's claims and gather further evidence, the court has ordered a polygraph test for the suspect. The test will be conducted by forensic experts at the Central Forensic Science Laboratory (CFSL).

The test involves attaching sensors to the subject's body to monitor physiological responses such as changes in respiration, heart rate, and electrical conductivity of the skin. These responses are believed to indicate deception when a person tells a lie.

Reliability and Controversy

Polygraph tests have been a subject of debate for decades. While some believe that they can provide valuable insights into a person's honesty, others question their scientific accuracy and reliability.

Critics argue that physical factors such as stress, anxiety, and medical conditions can influence the results, potentially leading to false positives or negatives. Additionally, some studies have suggested that skilled liars can manipulate their physiological responses to deceive the test.

  4. What are the ethical concerns with polygraph tests?

    • Polygraph tests raise ethical concerns related to privacy, potential for false accusations, and the possibility of coercion.
  5. What are the future prospects for polygraph testing?

Conclusion

The Sanjay Roy polygraph test is a significant development in the Kolkata rape-murder case. While it may provide additional insights into the suspect's involvement, it is important to approach the results with caution and consider both their potential benefits and limitations. As advancements in lie-detection technology continue, the debate over the efficacy and ethical implications of polygraph tests will likely continue for the foreseeable future.
