Question

in the case of schenck v. united states the supreme court ruled that
the espionage act was unconstitutional.
charles schenck had been falsely accused.
speech aimed to potentially create danger could be banned.
the first amendment had no limits.

Explanation:

In Schenck v. United States (1919), the Supreme Court, in an opinion by Justice Oliver Wendell Holmes Jr., held that Schenck's actions (distributing leaflets opposing the draft during WWI) presented a "clear and present danger." This case established the principle that speech which poses a clear and present danger (here, potentially interfering with the draft and military recruitment) is not protected by the First Amendment. The Court did not rule the Espionage Act unconstitutional (it was used to prosecute Schenck), nor that Schenck was falsely accused. And it firmly rejected the idea that the First Amendment has no limits - the "clear and present danger" test was a limit on free speech in certain contexts.

Answer:

speech aimed to potentially create danger could be banned.
