"Drones have been used as surveillance but also as killing devices, particularly in Afghanistan and Pakistan, in the war on terrorism. Hundreds, almost surely, have been snuffed out by these machines, which kill reportedly kill far more civilians than targeted militants. Credible reports indicate that the CIA has a favorite practice of targeting rescuers who show up to help others hurt by these strikes. [...] To be clear, I am not suggesting that American politicians and law enforcers will soon be blowing up Americans on American soil with these drones. But we can nevertheless draw some troubling conclusions."
