During yesterday's protest armed diplomatic police arrived, first three, the six, then back to three when they realised the embassy was not being stormed by anarchism, as was alleged last year.
A video of last year's protest is here, in which one journalist had his camera flash smashed and this journalist was batoned across the leg.

The police were very unhappy at first about being filmed and halted my filming, but as protestors and myself explained the reason behind the protest they calmed down and actually began to take an interest in the story.
Then as things calmed down the police decided to use stop and search powers on several of the protestors. Another two police, believed to be from last year's protest, arrived. The male officer really didn't like me, glaring, then smiling, then making a gesture to his baton.
