Police reports of mock suspect interrogations: A test of accuracy and perception.

A 2-phased experiment assessed the accuracy and completeness of police reports on mock interrogations and their effects on people’s perceptions. In Phase 1, 16 experienced officers investigated a mock crime scene, interrogated 2 innocent suspects—1 described by the experimenter as more suspicious than the other—and filed an incident report. All 32 sessions were covertly recorded; the recordings were later used to assess the reports. In Phase 2, 96 lay participants were presented with a brief summary of the case and then either read 1 police report, read 1 verbatim interrogation transcript, or listened to an audiotape of a session. Results showed that (a) Police and suspects diverged in their perceptions of the interrogations; (b) Police committed frequent errors of omission in their reports, understating their use of confrontation, maximization, leniency, and false evidence; and (c) Phase 2 participants who read a police report, compared to those who read a verbatim transcript, perceived the process as less pressure-filled and were more likely to misjudge suspects as guilty. These findings are limited by the brevity and low-stakes nature of the task and by the fact that no significant effects were obtained for our suspicion manipulation, suggesting a need for more research. Limitations notwithstanding, this study adds to a growing empirical literature indicating the need for a requirement that all suspect interrogations be electronically recorded. To provide a more objective and accurate account of what transpired, this study also suggests the benefit of producing verbatim transcripts.

Is a Plea Really a Bargain? An Analysis of Plea and Trial Dispositions in New York City

The study challenges the common notion that plea bargaining is necessarily beneficial to defendants. It examines the factors influencing the likelihood of taking a misdemeanor case to trial, and the probability of acquittal upon reaching trial. Defendants charged with more serious crimes, persons crimes, crimes with victims, and represented by private attorneys were more likely to go to trial than to be pleaded out. By contrast, very few factors influenced trial outcomes, and the effect of race was fairly weak. Perhaps most important is the finding that two in five cases going to trial resulted in acquittal, showing that guilt is not a foregone conclusion which may provide leverage to defendants in the plea-bargaining process.
