Some people broke the law, and the poster can be held accountable for successful incitement. It's not the post that broke the law per se.

You can yell fire in a crowded theatre. Just hope you don't cause a panic or you'll be in trouble.

Well, the test is if it's directed to and likely to cause a panic (in the US). So if you avoid causing a panic by sheer luck - like something counteracts your yelling and everybody settles down again, and that's the only reason nobody was crushed - you're still in trouble.

Though moral luck is certainly a thing in general, where negligence and risk-taking is not a crime until it goes wrong.

Aware of the US distinction, and it's mostly sensible. I believe in the US you actually can yell "fire" in a crowded theatre and if nothing happens, you'll be given the benefit of the doubt. As it should be.

Anything else a genuinely slippery slope.

But what if laws get interpreted through an ideological lens, and the person shouting happens to be a fellow member of the "Pro-Trampling Party"?

Then that'll be factored in as intent and they'll be held accountable for the consequences - not the speech itself.

The important part is that yelling "fire" is fine if the entire theatre laughs it off.
