In a landmark ruling in US v. US District Court, the Supreme Court unanimously rules the government must comply with the Fourth Amendment when surveilling an alleged domestic intelligence threat. The majority opinion says, "The price of lawful public dissent must not be a dread of subjection to an unchecked surveillance power. Nor must the fear of unauthorized official eavesdropping deter vigorous citizen dissent and discussion of Government action in private conversation. For private dissent, no less than open public discourse, is essential to our free society."
