The other discussion made me realize I was going to start a thread on this earlier this month.
These things are a disgusting nuisance. They are always trying to get up on to my lawn (we have a fence limiting them), and they shit everywhere. Our neighbors (fence-less) have them waddle their disgusting asses up onto their lawn all the time and they drop shit logs everywhere.
So: I don't think they are protected, so there must be some flexibility on how to handle them. What can we do? I know there are mechanisms to scare them away. But can we airsoft their asses? Hit them with other projectiles? Call them bad names?
