THE CHAIN OF EVENTS THAT BEFELL actor-politician Vijay’s rally on September 27, killing 41 and injuring dozens in Karur, Tamil Nadu, is still being unpicked, but some facts are indelible. Permissions were granted for far fewer than the 25,000 (police estimates) to 60,000 who turned up. The actor’s arrival was rescheduled, and even as his caravan idled, the restless crowd surged forward. Barricades were bent and the stampede was sudden, brutal and uncontainable as the crowd folded in on itself.
