The nearly week-long protest of thousands at Chennai's Marina Beach was remarkable not just because of its monumental scale - very often, the head count touched 15,000, according to the police - but also because of the determination of its young leaders to keep it apolitical and peaceful. That changed his morning, with some policemen complaining of being attacked with stones as they tried to disperse the crowd which wants Jallikattu, the bull-taming sport, to be made legal again. Huge clouds of smoke were seen at a police station near the beach where vehicles were set on fire, according to some reports.
