In fact I recall it was almost used on a PETA or some other outfit's member who was spooking fish by throwing rocks into the pool on the trout stream where a friend was trying to present a dry fly. My friend finally had enough, pulled his sidearm and pumped about three shots right at the feet of the Enviro. Realizing he'd brought rocks to a gunfight, the idiot was last seen breaking trail through the tall timber at a full run. Maybe not the recommended solution but it sure as hell worked!
