Miranda v. Arizona · ¶158

The second point is that in practice and from time to time in principle, the Court has given ample recognition to society’s interest in suspect questioning as an instrument of law enforcement. Cases countenancing quite significant pressures can be cited without difficulty, and the lower courts may often have been yet more tolerant. Of course the limitations imposed today were rejected by necessary implication in case after case, the right to warnings having been explicitly rebuffed in this Court many years ago. Powers v. United States, 223 U. S. 303; Wilson v. United States, 162 U. S. 613. As recently as Haynes v. Washington, 373 U. S. 503, 515, the Court openly acknowledged that questioning of witnesses and suspects “is undoubtedly an essential tool in effective law enforcement.” Accord, Crooker v. California, 357 U. S. 433, 441.
