Instead of just blowing them up/shooting them down why not figure out how to bring them back to your shop with minimal damage. Then you could reuse the parts to take more down.
granted there are risks to this and its probably easier said than done, but it would be freaking hilarious if enough were caught to swarm the skies during a presidential speech out on the white house lawn. just returning them to sender you know. Not a threat to anyone's life mind you...non violence is the way to go. I am sure anti-aircraft guns would be going off like mad and scare the heck out of all the state worshipers. I would be a poetic protest.
