Masks don't work. Forcing children into them was evil.

The agency’s director has said, repeatedly, that schools without mask mandates have triple the risk of COVID outbreaks. That claim is based on very shaky science.
...
But the Arizona study at the center of the CDC’s back-to-school blitz turns out to have been profoundly misleading. “You can’t learn anything about the effects of school mask mandates from this study,” Jonathan Ketcham, a public-health economist at Arizona State University, told me. His view echoed the assessment of eight other experts who reviewed the research, and with whom I spoke for this article. Masks may well help prevent the spread of COVID, some of these experts told me, and there may well be contexts in which they should be required in schools.
But the data being touted by the CDC—which showed a dramatic more-than-tripling of risk for unmasked students—ought to be excluded from this debate. The Arizona study’s lead authors stand by their work, and so does the CDC. But the critics were forthright in their harsh assessments. Noah Haber, an interdisciplinary scientist and a co-author of a systematic review of COVID-19 mitigation policies, called the research “so unreliable that it probably should not have been entered into the public discourse.”
...
Still, the publication and agency endorsement of the Arizona study is especially demoralizing. How did research with so many obvious flaws make its way through all the layers of internal technical review? And why was it promoted so aggressively by the agency’s director? I reached out to Walensky’s office to ask about the study, noting its evident limitations and outlier result. How, if at all, does this research figure into the agency’s continuing guidance for schools around the country? The CDC did not respond to my inquiries.
With Biden in the White House, the CDC has promised to “follow the science” in its COVID policies. Yet the circumstances around the Arizona study seem to show the opposite. Dubious research has been cited after the fact, without transparency, in support of existing agency guidance. “Research requires trust and the ability to verify work,” Ketcham, the ASU public-health economist, told me. “That’s the heart of science. The saddest part of this is the erosion of trust.”
