In 1928 there was a court case called "Olmstead v. United States" in which the government tapped a telephone wire (relatively new technology at the time) and caught a Roy Olmstead and several others who were allegedly distributing Alcohol, which violated the National Prohibition Act.
One of the justices, Louis Brandeis, argued that the government's actions were not lawful because it violated the principle which the Fourth Amendment stood for; here is a quote of his dissent:
Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well meaning but without understanding.
