Second pic shows one of the many successful incursions to block traffic in Whitehall, the police response to temporarily arrest, drag to the side, and de-arrest protestors, and on the right, one of the thirty 'permanent' arrests later in the day when the demonstrators blocked the whole of Whitehall on the way down to Parliament Square - a legal observer is watching the arrest closely.
