There was a mob outside of the Threadneedle Street branch of RBS in London.
They smashed the windows and invaded the building.
The press is referring to them as anti-capitalist protesters.
Rife with apparent contradictions, this situation, an outgrowth of the generic protests of the G20 meeting, is relatively easy to analyse.
The protesters are bored, idle and ill-informed. The police are edgy, ill-informed and have developed a siege mentality.
The outcome was never bound to be good.
