Discuss the evolution of standards the Court has used to adjudicate freedom of expression from Schenck to Brandenburg. In your answer, explain why the Court has not adhered to a single position, changing standards depending on the circumstances of the case. Why has the Court been more willing to restrict freedom of expression in certain times and has allowed more liberal standards at other times? Are you satisfied with the standards that the Court has provided? Do you feel that the standards should be more or less precise, allowing for more or less freedom in interpreting the standard? Why?
