nightmarebeforechristmas - there's nothing to "admit": I am merely telling you what I saw.
expatinscotland - actually I wasn't just "stood there". A lot of shoppers were just "stood there" though. Should they "think black burning shame" of themselves too?
I was shouting at them not to do it, as I did when I saw people attacking each other in Parliament Square, climbing and attempting to burn the Christmas tree in Trafalgar Square, knocking over postcard stands in Piccadilly Circus and breaking windows in Oxford Street.
I helped form a human barrier around a policeman who had been assaulted in Leicester Square and offered his colleague the small first aid kit I had which meant I would've had to go without later. Many backed me up in that but you didn't see any of that on the telly though, did you?
What did you want me to do: take them on myself, on my own?
