- Summary
- On 20 December 2019, the Chilean security forces used unprecedented quantities of tear gas within a relatively small area against people engaging in peaceful and unarmed protest. Using visual open source analysis and fluid dynamic simulation, we measured the concentration of tear gas in air and on the ground to estimate the scale of health risks posed on civilians on this day.
