Just because smoke makes you cough and possibly your eyes burn, does not make it tear gas. Much like seasonal allergies does not mean I have COVID-19. Tear gas is awful. Having been told (and watched to my laughter) friends going through Academy getting pepper sprayed, there's no way in hell they're going to throw a canister of that out and then run into it with no sort of protection from it. It was smoke. It's been said by the police there and those reporting on it that no, tear gas was not used. Smoke, and pepper bullets.
