As I get ready to go film one of the Swoops to occupy the location of Climate Camp in London, I read Tony Benns view about political change
"This is how I believe change occurs. If you raise an issue, it's usually ignored. Then if you go on, you're labeled as mad. If you go on further, you're dangerous. Then there's a pause. Then you can't find anyone at the top who doesn't claim to have thought of it in the first place. That's how progress occurs."
In which case, where along this road towards change are the Climate Campers?
"Well, I think they're beyond madness," Benn says, "and halfway beyond dangerous towards that pregnant pause"
