the problem with drones...
... is that they are too easy to operate, hover capable and can be equipped with cameras.
Any perv can buy a cheap camera equipped drone and fly around looking though bedroom windows just as any small criminal can use one to scout houses to see if no one is home.
If I noticed a drone hovering over my backyard at a low enough altitude for a possibly equipped camera to be looking inside my house I'd not only feel uncomfortable with it but threatened as well and honestly were I to have the means to rapidly ground the thing, I would.
I appreciate the hobby of operating R/C vehicles and I admire what some people can make their chosen craft do but my backyard is not the place to do it in, go to a local R/C airfield.
