It's a small detail but somehow it tells you so much:
Citizens, nearly all on the side of the protesters, left their front gates open just a little to offer those of us fleeing the police an escape route.
As we caught our breath in someone's driveway, I asked a man in his mid-30s whether he had witnessed anything like this before. "Over the last two weeks," he told me, "between the debates, the number of people in the street last week, and the violence nowno. I've never seen anything like this."
