If the drones were totally automated, they would need to have some sort of image recognition software in them if you were after a specific target, as even GPS has a small margin of error. You could add a larger explosive to make up for it, but you are limited as to how much payload you can fit into a drone. Even worse, long distance flights would require some sort of effective AI to avoid colliding with tall buildings and other obstructions. Lacking that, it would need someone to manually pilot that thing, which opens him up to jamming and radio direction finding. Even worse for the would-be drone pilot, your typical radio frequencies for commercial drones are in the 2.4 and 5 ghz range, which is pretty much line of sight and limited in range.
In the current situation, most commercially available drones you can buy have to be manually controlled by radio. So, if you were a would-be peeping tom wanting to get some racy footage of some woman, someone with a directional antenna and receiver should be able to zero in on your position and track you down. Of course, this assumes you have such equipment and are on the ball enough to use it. Any idiot can buy a drone but most people don't have the knowledge or inclination to employ effective countermeasures.
