By the way, advocating shooting down drones is stupid. The idea that every drone is some kind of government spy device is stupid.
The US military trains their operators on drones here in the US. My son's best friend is a bombadier for Predators operating in Afghanistan, and he is based at an air base in Missouri. He trained in Texas.
In addition, they are used for everything from exploring for oil and minerals, to mapping, to forest fire monitoring.
