Sure, but this one cop was protecting an area where the protesters had not yet accessed. That entrance might have been a "red line". We're speculating hard here, I'm unaware of a report on this yet, but the details should trickle out over time. As things stand, I'll give the cop the benefit of the doubt and assume he was justified in his actions.
