So people can bring down the drone and score some fun “non lethal” toys.
A police drone has a more limited ( camera ) field of view, audio, general situational awareness. So I see the possibility for more mistakes. Miss fires, bad targeting. Mass targeting.
Being a police officer is a difficult, dangerous job. But distancing the officer from the citizens makes the officer a more dangerous force. Be it technology or training that infers an us and them mentality. More distance between us and them, dehumanizes both.
