Most decided to leave, and later a visit was made by a large crowd at the police station where our comrades were known to have been taken.
text from IMC London.
along with that and shutting off that entrance to the london overground it seems like the authorities did a pretty good job of causing disruption, even if they prevented the 2 (at one point 3?) separate groups of demonstrators and concerned passers by from having a wider impact.
Also it was nice to hear the english and greek chants echoed back from across the street by the larger number of demonstrators gathered there... the greek language sounds absolutely fantastic for angry chants by the way, even if like me you don't understand a word of it.
