> You might think drones would already be ubiquitous.<p>Yes. I don't understand why they're not all over the place already.<p>> There are, however, Federal Aviation Administration restrictions on the use of unmanned aircraft systems, restrictions that date back several years.<p>Well, there are drones, and then there are <i>drones</i>. Anyone can attach a camera to a helium balloon, and I don't think the FAA would mind much. It wouldn't take much of a hacker to make the thing controllable, at least in a low-wind environment. And then there are hexacopters, etc.<p>Why aren't lots of people doing this? Why aren't the front pages of the supermarket tabloids full of celebrity complaints about balloons with cameras hovering over their property? Why don't we see these at sporting events and outdoor concerts and other places where some people have a great interest in circumventing restrictions on photography? Why aren't kits for these things being advertised? It's a mystery.<p>NOTE: I am not <i>suggesting</i> that people should, say, spy on celebrities. I'm merely noting that lots of people are already trying to do so, and I don't see why they are not using these methods.
