200? Looked about 50 of them with a women pushing a baby in the buggy with an old man with his walking stick next to her holding up the traffic along the Old Stein when the rest of the 'protesters' were way up ahead. They made themselves look twats to be quite honest.
200 is the police estimate but they are probably justifying having 200 officers on hand to police the so called protest. In reality all they needed was a dozen foot officers with rubber bullets and a couple of water cannons.
