There is concern that the protests that have been heavily flagged on the internet and in the May Day Monopoly game guide pamphlet will not be the focus of any trouble. We don't think so. But we cannot be sure. We think we know who they are. Intelligence can help us prepare, but it won't get someone arrested.
Intelligence can also be wrong.
We won't really know what we're dealing with until the day. A lunchtime protest takes over Upper Street, Islington, one of north London's busiest roads. By early evening riot police move in to clear the road and sporadic fights break out as the 200 protesters are driven towards King's Cross station. Violence erupts when anarchist protesters attack a McDonald's restaurant and there are sporadic clashes with riot police across the city.
