An event at the Literature Festival in Rajasthan's Ajmer where Naseeruddin Shah was to deliver a keynote address this evening has been cancelled amid protests by right wing groups over the veteran actor's comments on the Bulandshahr mob killing of a police officer earlier this month. Groups including the Bharatiya Janata Yuva Morcha, shouted slogans at the LitFest venue against Naseeruddin Shah, who had in an interview with an NGO earlier this week remarked that the death of cows was being given more importance than the death of a policeman.
