All of those full face respirators the cops are wearing would also work great for healthcare workers, who are still dealing with COVID-19. Specifically anything with pink cartridges has a P100 particulate filter, the highest level of filtration (99.97% vs N95 95%). When you see a picture of cops wearing or holding respirators, you should think of the nurses, EMTs, and vulnerable people that have been deprived of that PPE, just so the cops don't have to think about which direction the wind is blowing before they open fire on peaceful protestors.
