You can yell it if there is a fire; if there isn’t likelihood of causing a stampede; if you on stage and it is part of the show and others I can’t think of at the moment.
As you said, it is legal to yell fire but there are potential consequences if you do depending on the circumstance and outcome.
First you say it’s legal to yell it then you say there are consequences. That seems to be contradictory because if something were legal there would be no legal consequences.
But to the point, this article has a non lawyer Emma camp a philosophy major lecturing us on constitutional law. Gee, for those of us with law degrees this is pretty funny stuff. Schermer ought to vet his writers a little more carefully. Some moron saying a Supreme Court justice doesn’t know the law is pretty vile.
And by the way, Alito is perfectly correct.
