Damn, I so wish I had seen that.
Nearest we have had round here is when the pikey's were encamped on a big byway. DHSS had bought a big 4x4 wagon to get there to pay them each week. Eventually a certain member of the local district council who was a hellva lot more savvi than the rest, arranged for a large slew to track up there during one night. It dug a ditch - deep & wide from 1 end to the other of where they were camping. He had certain local escorts helping with may have at first glance, looked like shot-guns in their hands. Long and short of it was that by the time the digger had got near their caravans, they had scarpered:-D. Good for him having the nerve to take the b****ds on. More than most of the wet civil servants will.
