Policing the Drunk Driving Problem: A Longitudinal Examination of DUI Enforcement and Alcohol Related Crashes in the U.S. (1985-2015)


Purpose: This project examines the relationship between police enforcement of driving under the influence (DUI) and fatal alcohol related crashes.


Method: This article merged data from several sources to fit several 3-level growth curve models that assess the relationship between DUI arrests and fatal alcohol related crashes in U.S. counties from 1985-2015.


Results: The findings indicate that increases in DUI arrests are related to decreased fatal alcohol related crashes during the period. However, the two are not linearly related and the relationship varies across states.


Conclusions: The non-linearity indicates there is a point of diminished returns where increased arrests are no longer related to reductions in fatalities. These findings suggest that policy makers should explore alternative methods of reducing crashes to supplement enforcement efforts such as addressing problems of alcoholism and traffic safety.

Immigrant Threat and Latino/a Disadvantage: Disentangling the impact of immigration attitudes on ethnic sentencing disparities


The criminal justice system has increasingly been relied upon to address immigration apprehension, resulting in concerns that this institution will be abused in an effort to indirectly address this perceived social problem.  The consequences of such an approach will likely extend to Latino/a populations as a result of rhetoric linking ethnicity, immigration, and crime.  Despite popular theoretical frameworks suggesting that disadvantage will vary according to the size of the population and the extent of perceived threats toward this minority, many neglect attitudinal measures or fail to measure actual criminological outcomes.  This project addresses this oversight by exploring potential mediating effects of attitudes on the relationship between population measures and ethnic sentencing disparities.  After fitting multilevel models nesting cases within counties and states, the results indicate that there is significant variation across all levels.  While greater disparities in Latino/a sentencing were found in counties with greater Latino/a populations, this relationship was nonlinear.  Additionally, state level measures of immigrant threat attitudes appear to be stronger predictors of Latino/a sentencing disparities.  These contextual effects are more influential than offender level ethnicity, supporting threat hypotheses and suggesting that measurement of this concept should not be limited to offender ethnicity and population characteristics alone.
