There are reports of the police having to charge the demonstraters in the City of London, but given the changed nature of the police force in the U.K., as described in several posts below, I wouldn’t be quick to ascribe blame even to this lot. However, this is a very interesting report from the BBC live blog:
1653 The BBC’s Mark Georgiou says: Until now the climate camp protest has had a peaceful, almost carnival atmosphere. However, in last half an hour a different sort of demonstrator has started to arrive – clad in black, masked and aggressive.
The paramilitary wing of climate protesters? British left/environmental protests — anti-nuclear in the 1980s, anti-roads protests in the 1990s, have often attracted this sort. I’d imagine that climate is latest cause on which they’re hanging their hats.
