No, but none of those are free speech issues. Swatting involves deceiving law enforcement; ICOs were something nobody with any real law enforcement or policy power understood well at the time but they’ve been taking the time to learn (emphasis on time) and death threats are generally more an issue of resources. Any dumbass can create an anonymous email address and send threats. Unmasking all of the dumbasses willing to send them is generally more resource intensive than providing temporary protection and investigating the veracity of the threats or the likelihood they will be carried out; but if you did unmask them it would typically mean at minimum a trip to the psych ward for them to be held and evaluated.
Note also that the comment I was originally replying to was saying we already have too many restrictions on speech. So they'd presumably want to loosen those things even more.
We could easily make the penalty for SWATting life in prison. If you got caught the only free speech defense I could imagine would be that you sincerely believed that SWAT was needed and you were mistaken. Sometimes that defense would work, but I can imagine all kinds of scenarios in which the defense would be useless, e.g. you did it to the same guy multiple times, or you don't live anywhere near the location you sent SWAT to
I see more "grudging acceptance" than any sort of good control.
And if that's what the people want, that's fine.
But in my view, if we wanted to do better on those things, we should have the freedom as a society to do those things. That's the place I argue against "free speech absolutism" from. Would we then change our mind later, or put different regulations in place? Quite likely! But that's perfectly fine. The only way to not change is to die.
