Zoe Williams - one of the heroes of today.
Quote from Ms Williams: "When I asked them what their motivation was they just said 'we're doing it for fun'. I don't understand that."
Once again, mixed with the worst of human behaviour is the best. The Coppers on the street trying to contain the trouble, and help their injured colleagues, and genuine protestors like Ms Williams and Aaron Porter.
A word of advice to any wannabe protestors - injured officers = PISSED colleagues.
