Tear Gas Time!
I can attest. I was in the subway headed toward Baquedano, we got to a stop, the doors opened, and my eyes and nose started burning. Everyone covered their faces, and we got an announcement overhead that I couldn’t understand. No one said anything. When I got to my stop and went above ground, there were riot police everywhere, lined up orderly on block corners, standing quietly with shields. The protest had dispersed at that point.
