You aren't familiar with the 10th Amendment, eh? Don't worry, pretty much no one else is, least of all today's politicians. This needs to stop. This really needs to stop. That partial quote came from one of the worst Supreme Court decisions in the history of the Supreme Court, and it was uttered as an analogy, trying to equate speaking out against conscription into WWI with falsely shouting "fire" and causing a panic (falsely is always, always, always omitted, when it is, in fact, the most important bit of the whole thing, as is the ending phrase). This putrescent opinion was used to justify lower court decisions upholding the prosecution of Charles Schenck and Elizabeth Baer under the Espionage act of 1917. It is in every way a piece of shitty jurisprudence and yet somehow manages to justify all sorts of bullshit regarding the First Amendment and prior restraint. STOP USING IT. It's terrible and infantile and Oliver Wendell Holmes ought to be burning in hell for all eternity for delivering it.
