Protestors here in Chicago made easy work of the barriers around the United Center, we were there as they quickly dismantled them and poured into the breach. In about half an hour most of them were cleared by huge numbers of riot police. Four people were arrested. Authorities spent most of the night and this morning reinforcing the barrier, adding more concrete and steel brackets and surveillance cameras. #chicago #dnc #democraticnationalconvention #protest #gaza #barrier
