[quote]With that ruling, the Court overturned the Schenck decision that had introduced “shouting fire in a crowded theater.” No longer was “clear and present danger” a sufficient standard for criminalizing speech. To break the law, speech now had to incite “imminent lawless action.”
So if a court can prove that you incite imminent lawlessness by falsely shouting “fire” in a crowded theater, it can convict you. If you incite an unlawful riot, your speech is “brigaded” with illegal action, and you will have broken the law. But merely falsely shouting “fire” does not break the law, even if it risks others’ safety.
