True Threats have a legal standard and specificity of person, place, and time are elements.
Criminal Threatening usually has a state statute.
The summary sounds much more like "muh feels" and conclusory pleading so it's probably not true to the legal standard.
How many arrests were made?

Posts are almost always powerless and can just get you in trouble. Don't do it to blow off steam. Or for clout.
Not worth it, get out there and take action if you mean it. Don't blab about illegal fantasies.
