Actor Kamal Haasan said today that a series of videos uploaded on social media that show policemen indulging in arson in Tamil Nadu has left him "shocked". NDTV cannot verify the authenticity of the videos, which have been tweeted by Kamal Haasan and other celebrities like actor Arvind Swamy. "I hope some sort of reasonable explanation is given to us which will calm us down," said Kamal Haasan at a press conference today in Chennai, which saw spasms of violence yesterday after a week-long protest demanding the return of Jallikattu, the bull-taming sport, came unhitched from a resolute peace maintained by thousands of participants who camped out at Marina Beach.
