Drones have been unable to operate when sieges like Poly U and CUHK happen because drones like DJI operate the GPS is shut off in the software because it is Chinese built. I know some scouts use drones and it could be useful to prevent getting flanked and stampedes like in Yau Ma Tei. Cost should be about 10,000HKD per drone, but drone would be able to outmaneuver anti drone measures and GPS jammers
