What's needed is a drone spotter smart phone app that detects the camera and feeds an image of your bare ass to the optical receiver. It might be called iMoon.

Not a bad ideal Steve;

Maybe change the Apple (find my iPhone) app to (find my terrorist) app - sorta loose a few hundred iPhones where the terrorist can find them.

Once the phone is activated and confirm that yes a terrorist has it - launch a drone strike tuned to that phone location.
