Introduction
The Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, enacted to replace the Code of Criminal Procedure, 1973 (CrPC), significantly reshapes the role of the police in investigation and preventive action in India. BNSS is part of a broader criminal law reform that also includes the Bharatiya Nyaya Sanhita (BNS), 2023, and Bharatiya Sakshya Adhiniyam (BSA), 2023.
Under the BNSS, the police are entrusted with enhanced responsibilities to not only investigate offences efficiently but also to prevent crimes before they occur. The law emphasizes technology-driven policing, citizen-centric safeguards, and speedy justice.
This essay explores in detail how the police function under BNSS in relation to investigation and preventive action, including relevant sections, procedural mandates, technological integration, and constitutional safeguards.
