Stephen Petty's @pettypodcast1 remarks to the North Carolina Legislature on the futility of masks as a health intervention. Long but worth reading:

"Regarding the proposed language:
This language is simply nothing more than a power grab in the name of public health and safety with implementation language not based on any real science.
If moved forward, this proposal will be impossible to implement by the public due to incorrect and vague language, will provide no effective mitigation from infectious diseases, and will actually cause great harm to the public based on misleading so-called science. The harms will be greatest to our children.
Some key points regarding the actual science in my 80+ slide presentation and three supporting documents (attached):
-CDC cannot be trusted with the science – (masking – no masks, masks, no masks, masks – no science changes its position 180 degrees twice in two years. The 6-foot distancing rule has no basis in science; Dr. Fauci recently admitted this.
- Face coverings (masks) cannot and do not protect individuals from respiratory diseases - >100 year old science beginning at least in 1919.
Face coverings and respirators in your proposed language have been conflated. Respirators are PPE, face coverings are not – see either CDC or OSHA.
-Masks by definition cannot be sealed; masks that can seal are called respirators.
