The blockade of the side entrance did not, unfortunately, receive total support from all the protesters in that spot. The PLP (Progressive Labor Party), for instance, were too busy standing on the sidelines chanting monotonously for "Communist Revolution" to help out by linking arms. One of them actually pulled back a comrade of his who was getting too close to the action, telling him he was needed elsewhere. I left before noon, however, so it's possible they might have helped out later.
