I didn't bother. Its in the media, its debated. Go look for opposing views and you'll find them.Funny how you couldn't provide any of these "verified" studies.
This article mentions several recent studies -- not old studies that dealt with influenza viruses -- that support the use of face masks: https://www.nature.com/articles/d41586-020-02801-8
And more evidence is coming every day: https://www.latimes.com/science/sto...r-masks-we-could-save-more-than-671-000-lives
As for schools, different story, as there is emerging evidence that transmission from yoing children to adult is limited and it doesn't appear that elementary schools are seeding community transmission. The data isn't perfect here and it doesn't mean that kids can't get infected and spread COVID (they can): https://www.nytimes.com/2020/10/22/health/coronavirus-schools-children.html
I love the "there is emerging" well, many people have been saying this since the beginning, or if you want to be more prEcise, "near the beginning"
