K.P.S. Gill’s imprint on the history of counter-terrorism is incomparable. The comprehensive defeat he inflicted on Khalistani terrorism in the Punjab and his contributions to policing in regions of widespread disorder were exceptional, exemplary. He encapsulated the masterful strategic approach to terrorism and crisis policing as no other leader has in recent history. But Gill was much more than an exceptional police leader. His achievements go beyond his life, beyond personality, into the realm of ideas. He had a vision that was not rooted in the perspectives of a policeman. He was, in fact, one of the most profound thinkers of our age, focusing on conflicts across the world, and the constantly fraught struggle for democracy. He was a man of heroic proportions, a true hero, as few are in this age. This volume is an effort to honour K.P.S. Gill by keeping under continuous and rigorous scrutiny the many issues on which his career and his mind were focused. It brings together leading commentators and exceptional international scholarship on a wide range of contemporary issues relating to ongoing and emerging challenges of security in an increasingly uncertain global context.
