Remember that guy in Granby, CO, who got so fed up with the city council that he built an armoured shield around his bulldozer, got in it, drove downtown and destroyed city hall and the library ? It was a year or two ago I think.
Yep. Back in 1995, IIRC, there was another incident in New Hampshire. Although it wasn't an eminent domain matter, it was a clash between local government and property owner over a piece of land. Google "Carl Drega".
