Police grab a guy
As well as the tents, there was also a sound system and two bands playing, and people began to dance and others to have picnics and to chalk slogans and drawings on the road. An MP made a short speech, saying that he and several other members supported the right to protest and were here to see what the protesters had to say and also to see that they were treated properly by the police.
Although for the first half hour or so the police seemed content to watch the protest, scuffles started to develop around the edges. Most seemed to be caused by groups of police grabbing masked demonstrators and attempting to unmask them. I got the impression that there were many of the police who were there looking for trouble, and wasn't surprised by the later reports of police smashing property and man-handling demonstrators, as well as the arrests. But I left shortly before 2pm to go to the march from the US Embassy.
