While some social media users commenting on the story think it's a good investment, others say it will just make people try to knock the drones out of the sky. The idea "needs more thought", says one person writing on the Times of India website , who adds that the drones will need to fly relatively low to target the pepper spray, and could end up being damaged. Others are concerned that the tactic will be indiscriminate. "Is using pepper powder on a mob, even if unruly, within the law?" asks one user. "Moreover, this showering of pepper can affect others in the locality or passers-by who are not part of the 'unruly mob'."
