As Director General of Police, Haryana, I have witnessed this transformation not just as an administrator but also as a practitioner, standing alongside my team on the front lines. Haryana now leads the country in implementing the new criminal laws (NCL), and I have seen every stage of this transition up close. We retrained investigators, redesigned workflows, and embraced new technology. The learning curve was steep, but reform was essential. When IPC Section 420 became BNS Section 318, and IPC Section 302 became BNS Section 101, investigators, many with limited formal education and training, had to unlearn decades-old practices and master an entirely new legal framework almost overnight.
