I personally would have SAID different things in March than Trump SAID. I'm not sure how much difference it would have made. I might also have panicked everyone into hoarding something weird, like say toilet paper.
But given Trump down played this, and he did early on, what should WE be doing NOW that we are not doing?
National mask mandate from the President? Really? Make it enforceable by Federal "mandate"? Then local police would have no purview and many would be directed to ignore the law, which likely is unconstitutional anyway without legislation, and perhaps even with. The local police enforce local and state laws.
Or we could allow each governor and mayor to respond to the local situation which will be vastly different from NYC to Boseman, MT.
We have a local mask "mandate" in Atlanta that really is nothing, it's entirely optional, I'd wage not a single ticket has been written. I see police out with masks around their necks, or in their pocket.
