[OLD FOOTAGE/NOT RECENT]
All this talk of chemical weapons lately reminded me of that two-week(ish) span of time at the end of January 2021 when the feds down at the ICE facility in Portland were spraying people with some kind of teargas using this weird tool that, iirc, was some kind of pesticide fogger that they decided to use to unleash chemical warfare.
There was no way to know what kind of chemicals they were using on us as there were no canisters left behind. People were guessing by the taste, smell, and symptoms.
