It appears that the anti-capitalist protesters see fit to rally to the cause only during daylight hours. A thermal imaging camera panning across the rows of tents in the grounds of St Pauls quickly spotted that during the night, the overwhelming majority of the cathedral's unwelcome guests disappear from the site. Presumably they head back to their comfortable, upper middle class homes where they can snipe at mummy and daddy for being stinking rich before heading off to their comfy feather beds for a good night's kip. Next day they return to their occupation of daytime protesters, calling in at Costa Coffee and other symbols of hated capitalism for breakfast.
I bet the church authorities are regretting their decision to let this mob of middle class muppets camp it up outside St Pauls. Personally, if I had to protest outside St Pauls, it wouldn't be capitalism I would be protesting against. Instead, it would be the appallingly expensive entrance fee that visitors have to pay to set foot in the Cathedral.
