We have beavers down here. Occassionally they damn up the pond behind my house, which is quite fairly common. You call up the city, and the city sets traps to relocate them outside the city. However, there were locals who scanned the radio waves listening to the city workers talk about where they are going next to capture a beaver. Even before they'd get to their destination, there would be 5 or 6 citizens who would be there to try to stop the city from removing the beaver. Eventually, the city workers had to start talking in code, i.e. beaver became acquatic engineer, so they didn't have to deal with the protestors.
