Every full face respirator you see riot (-causing) police wearing or holding has a P100 particulate filter and could have instead been used by a nurse, EMT, or an at-risk person for protection from COVID-19. And to have so many ready to go, the cops were likely just sitting on their stockpiles throughout that period of dire PPE shortage. If that PPE had been used for healthcare as it should have, the cops would have had to think twice before adding tear gas to the air during a respiratory pandemic.
