Just read through the Biggs file, most of it is like a bad high school report on the proud boys, there are a few pictures included, none that I can tell he is in the capitol but some outside of it. He admits to entering the capital but that the doors were wide open. Seems weak, I bet most of them are similar to this one.
I think the best analogy I have heard about wearing a cloth mask to protect yourself or someone else from the China flu is comparing wearing the mask for protection against covid to building a cyclone fence to protect you from mosquitoes. This virus is so small that only a level A fully contained suit would protect someone.
Even this level of protection doesn’t protect you from a virus.
