Fast forward a decade or two when the tech has improved a bit, and add a camera and facial recognition and let it rip on your target of choice. They get good at shooting them down? Make sure you send 50 of them instead of 1. [edit] It seems inevitable to me that this will happen at some point in the next few decades. It also seems inevitable to me that countries will enact laws to try and prevent it. But that it will happen anyway. No matter what law is created.
