Nice pictures. I was there..well, I was in the bar drinking while this was happening.
It looks a lot more orderly now, but earlier some of them had literally blocked off traffic during rush hour, causing complete gridlock. People were standing in the middle of the streets. Cars were stopping and chatting with pedestrians and giving high-fives, oblivious to the hundreds of cars and buses that needed to pass. Honestly, some of them needed a kick in the face.
Glad the police finally got it under control.
