I have seen a few people locally wearing respirators instead of masks. I saw a lot of protestors in the TV newsclips wearing commercial respirators as masks. Respirators have exhaust valves and as anyone knows are designed to filter incoming air for different types of particulates based on the respirator design and purpose. A respirator does not prevent airborne particulates from being expelled into the air by the wearer. If a COVID-19 carrier is wearing a respirator, it will not protect those around him from coming into contact with airborne particulates being exhausted from his respirator. I'm kind of surprised no one on the medical side has not mentioned this when they were stressing for people to wear masks.Were they masked and social distancing?
If they were singing hymns or otherwise worshipping, they would have already been arrested.
