99.9% of the time the drone is going to be worth way more than the package. Grabbing the cable and pulling the drone out of the sky for parts is more likely.

But what if you shot down 30 of them already? I suppose you could sell parts on the black market, but that would probably get you caught.

Eventually Wal-Mart starts sending out armed drones to protect the delivery drones. You'll need a constant supply of your own attack drones to fight against Wal-Mart's security drone. (Just kidding... I hope!)

This sounds ridiculous. How long did it take to see truck drivers taken hostage and payloads stolen?
