Notes

  1. In one of Sherlock Holmes' stories, as a suspect is nabbed and warned immediately of his right to remain silent, A. Conan Doyle pays glancing tribute to "the magnificent fair play" of British law. However, the Miranda rules go much further than the standard British warning. Whereas in pre-Miranda days the Federal Bureau of Investigation required a warning to suspects, Justice John Marshall Harlan noted in dissent that the FBI procedures fell easily short of Miranda's "formalistic rules" for the whole country. Harlan said, "There is no indication that FBI agents must obtain an affirmative 'waiver' before they pursue their questioning. Nor is it clear that one invoking his right to silence may not be prevailed upon to change his mind."

  9. The study gathered evidence on "confessions" before Miranda and "confessions and other statements" after Miranda. Because this latter category is broader than the first, it is impossible to meaningfully compare the two statistics. The law clerk who actually collected the data agrees that the figures from Los Angeles "prove nothing." See Paul G. Cassell, "Miranda's 'Negligible' Effect On Law Enforcement: Some Skeptical Observations," 20 Harvard Journal of Law and Public Policy 327, 332 (1997), quoting now-U.S. Court of Appeals Judge Stephen S. Trott, who collected the data.
  10. Data from L.A. are excluded for the reasons given in the preceding note; from the District of Columbia because police did not generally follow the Miranda requirements, and from Chicago because the data are limited to homicides. See Cassell, supra note, at 418.
  11. See Cassell, supra note, at 438-39. For further discussion of this estimate, compare Stephen J. Schulhofer, "Miranda's Practical Effect: Substantial Benefits and Vanishingly Small Social Costs," Northwestern University Law Review 500 (1997) with Paul G. Cassell, "All Benefits, No Costs: The Grand Illusion of Miranda's Defenders," Northwestern University Law Review 1084 (1996).

Thomas III, "Plain Talk About the Miranda Empirical Debate: A 'Steady-State' Theory of Confessions," 43 UCLA Law Review 933, 935-36 (1996), deriving lower estimate with which to compare studies.

  28. FBI clearance rates have been criticized as subject to interdepartmental variations in what constitutes solving or "clearing" a crime, but the figures used here come from the aggregate national clearance rate, comprised of reports filed by thousands of law enforcement agencies. Even if a particular city reported rates in a questionable fashion, our results would be unaffected if any manipulations did not change significantly in the several years surrounding Miranda or if any changes in the manipulations were relatively small in comparison to the total number of reports nationally. These are both reasonable assumptions. See James Alan Fox, Forecasting Crime Data: An Econometric Analysis 7 (1978), concluding that the problem of data manipulation is "not overly troublesome" for time series analysis that "does not involve cross-sectional data, but rather a time series from the same population"; Charles R. Tittle and Alan R. Rowe, "Certainty of Arrest and Crime Rates: A Further Test of the Deterrence Hypothesis," 52 Social Forces 455, 456 (1974), although manipulation is possible, "such biases would seem to be distributed throughout the various police departments so that the validity of a study which examines internal variations in the entire body of data . . . would be unaffected.".

  35. Compare Charles Murray, Losing Ground: American Social Policy, 1950-1980, at 117 (1984), reviewing crime statistics and concluding: "Put simply, it was much more dangerous to be black in 1972 than it was in 1965, whereas it was not much more dangerous to be white."
