For every good cause and every well-intentioned action, there are always people or organisations that will find a way to turn it to something less than good.
That is how I class the action by the police force in Lucknow, India. They've bought two drones which can carry the weight of pepper-spray canisters for crowd control as it'll be "better than a baton-charge".
Way to address the root of issues. Mass surveilance on citizens and gassing them isn't the answer. It can't be.
