They were not there as protestors (well, not solely), or tourists, they were there in their professional capacity as nurses offering first aid to a crowd of people.
and you arrested them Rahm (let's go all the way to the top, where the blame actually does belong and not to the poor damn cops who are just trying to feed their families)
how the hell does that make any sense at all? Even in war they let medics through (most of the time)
usually nurses and cops are allies, close allies. Nurses see the same shit and play by the same rules. *eh, throws hands up in the air* wtf guys?!
