Drones should have a "piñata radius" so if you're flying it close enough where I can hit it with a bat I should be able to. Like when I was at a skatepark and this drone nerd was pissing everyone off. The drone ended up in the lake pretty quickly.

Pinata radius might actually be legally allowable. Drone operators must maintain the safety of those in the area. Flying that close to a person with spinning blades arguably constituents an imminent threat to safety and it might be ruled justified to knock it out of the sky.
