A letter from the Deputy Commissioner of Police (DCP) prior to the June 4 RCB felicitation event at Vidhana Soudha raised several concerns, including the need for anti-drone systems and additional preparation time. The letter cited the risk of drone cameras being used by the public and reiterated that more time was required to organise such a large-scale event at a "vital installation" and heritage site. It concluded that the police would follow the government's final decision on the matter.
