I don't worry a bit about carrying, open or concealed, with a corona virus mask on. Sooner or later, they'd have to prove intent...and you'll win. You may be broke, the US supreme court may make the determination, but you'll be in the clear. Now a clown mask, or some other foolishness, well, some police beat-downs are justifiable, if you are that stupid.
Yes, but common sense should have the authority to make you say to yourself:....hmmm this might save me or a loved one from getting sick, or dead...
dot gov has the ability to say wear a mask, but not really the authority. Is it really enforceable, will it really hold up in court? (re: supreme court, above) No, and they know it. But if it convinces 50% of the population wear a mask in public, that *reduces* the chances that that particular 50% of the population will get or give CV (via that transmission method). Less infected folks (by whatever means) will equate to less transmission of the virus (by whatever means).
Goobermint can still kiss my ass, but I am wearing a mask when appropriate.
