Harassing a hunter is illegal under Massachusetts law, but that’s not stopping People for the Ethical Treatment of Animals (PETA) from launching a new surveillance drone dubbed the “Air Angel.” This drone is designed to follow hunters who are possibly engaged in illegal hunting practices.

For about $325, a person can purchase a drone from PETA’s catalog, and use that drone to film hunters who they believe to be engaging in illegal activity. The program went live on the first day of the Massachusetts bow hunting season.
