Reasons for Potential Unreliability of DNA Evidence: A Critical Examination

Author(s) Md. Imran Wahab, IPS
Country India
Abstract DNA evidence is widely regarded as the "gold standard" in forensic science because of its capacity to accurately identify individuals and exonerate the innocent. However, several factors cast doubt on its reliability in criminal investigations. This study offers a comprehensive exploration of critical issues influencing the trustworthiness of DNA evidence, including errors in evidence collection, overlooking additional DNA samples at the crime scene, the absence of credible witnesses during searches, and the lack of video documentation throughout the processes of seizure, transportation, and lab analysis. Other concerns include human errors, inconsistent DNA analysis protocols among forensic laboratories, and potential contamination during sample collection. Furthermore, the research delves into laboratory errors, subjective interpretations, and existing biases. There is an increasing worry regarding the excessive reliance on DNA evidence without sufficient investigative corroboration, along with the potential misinterpretation of statistical probabilities by jurors. The article also examines ethical issues surrounding the expansion of DNA databases, privacy violations, and familial DNA searches. Citing pivotal academic studies and landmark legal cases like those of O.J. Simpson and Amanda Knox, this analysis highlights the pressing need for rigorous standards to govern the ethical use of DNA evidence in the criminal justice system.
