This study examined whether public perceptions of police traffic stops and searches varied when participants were randomly assigned to receive various traffic stop and search statistics derived from research. We utilized an experimental information provision survey sent to head of households in South Carolina with an associated email address. Respondents were randomly assigned to one of three conditions: 1) a condition where respondents were presented statistics on contraband hit rates (i.e., rate at which contraband is found during a stop), 2) a condition where respondents were presented statistics on racial disparities in traffic stops, or 3) the control condition. Results from roughly 4,600 respondents indicated that research on traffic stops and searches could impact public opinion regarding whether the police should conduct more stops and searches. Statistically significant differences were found with the contraband versus the racial disparity conditions and with the racial disparity versus control conditions. Looking at the overall probabilities (without regard to the p-values for the differences), respondents who received the racial disparity condition were the least likely to agree that police should conduct more traffic stops and searches, while respondents who received the contraband condition were most likely to agree that police should conduct more traffic stops and searches. However, it should be noted that probabilities for all conditions ranged from approximately 32% to 38%, meaning that most respondents did not agree that more traffic stops and searches should be conducted.

Nearly all states, including Ohio, have laws increasing punishments for drug trafficking in or near schools, though there are long-standing concerns for how these laws function. With a novel inquiry of school leaders, the current study explores whether Ohio schools displayed signage that was viewable by the general public stating that drug traffickers could face enhanced penalties if the conduct occurred on or near school premises. The current study also sought to gauge school principal perception about the deterrence effectiveness of such signs and whether enhanced penalty laws should explicitly require that individuals know they are on or near school premises to receive a penalty enhancement. The results of this survey of Ohio school principals suggested that the vast majority of Ohio schools lack any signage seeking to notify individuals of enhanced penalties for drug trafficking or that generally seek to deter drug trafficking. The results also showed that a majority of Ohio principals believed that the Ohio Revised Code should require that individuals know they are on or near a school's premises to receive increased penalties for drug trafficking (e.g., selling drugs) on or near school premises. Policy recommendations informed by the above findings are discussed.
