IN-VEHICLE VIDEOTAPING OF DWI (DRIVING WHILE INTOXICATED) SUSPECTS. FINAL REPORT. VOLUME 2: OUTCOME ANALYSIS
This study examines the effects of in-vehicle videotaping on the prosecution and adjudication of DWI (driving while intoxicated) cases for each of two cities: Binghamton (NY) and San Diego (CA). The analyses consisted of a set of comparisons between a program group, DWI suspects who were videotaped in the field, and a comparison group, DWI suspects who were not videotaped. The analyses included the use of logistic or stepwise multiple regression to determine the case characteristics, including the use of videotaping, associated with each outcome measure. The outcome measures included the rate of conviction, the violation of conviction, the elapsed time between arrest and disposition, and whether the case went to trial. The results for Binghamton support the hypothesis that the use of in-vehicle videotaping increases the likelihood of a DWI suspect's conviction during the study period 1991-1993. While having a prior DWI conviction increased the likelihood of a suspect's conviction for the charge of DWI rather than the lesser charge of driving while ability impaired (DWAI), having a prior conviction and being videotaped increased that likelihood even more. In-vehicle videotaping was not associated with either the elapsed time between arrest and disposition or the occurrence of a trial, although the small number of trials limited the ability to draw meaningful inferences. The results for San Diego indicate that in-vehicle videotaping was not associated with the conviction rate, the violation of conviction, or the occurrence of a trial during the study period 1991-1993. It should be noted that for each agency, 97% of DWI suspects, including those who were videotaped and those who were not, were convicted during the study period. With such a high rate of conviction, the marginal effects of any intervention, including videotaping, would be difficult to detect.
