 But it was essentially a whole day where police kept firing tear gas, using water canyons to disperse crowds. And by the end of the day, by the time I was leaving the Nairobi Central Business District around 4.30, 5 p.m. to head back to the office, the streets were littered with empty canisters that have been exploding all day. The streets were painted literally pink because the water from the canyons has this pink dye.
