As you previously noted, the members of that community equally enjoyed the legal right to be protected from acts of lewdness performed by someone "under circumstances which he or she should know will likely cause affront or alarm."
That was her intent for marching up and down Main Street deliberately exposing herself.
Not just lewdness, remember, but “gross lewdness,” according to the law.
Does someone walking down the street minding their own business with no shirt on really rise to the level of public fornication? Is it “grossly” lewd, or merely lewd?
