Unmanned Drone on Drone Crime

Recently, an unmanned Reaper drone, a top of the line military aerial vehicle, shot down a target drone with a missile.  This is the first time in history that an unmanned craft has shot down another unmanned craft.  It is only a matter of time before these move from “unmanned” to “AI controlled”.  Keep in mind this was a military exercise, not something that happened on the battlefield, but it is a watershed moment.
