The Impact of Random Metal Detector Searches on Contraband Possession and Feelings of Safety at School

Weapons at school pose a danger to students as well as faculty. Educational administrators have attempted to reduce their prevalence by implementing random weapons searches in schools. This article examines the effectiveness of this approach using data from two geographically adjacent school districts in Florida (Miami-Dade and Broward). In the 1998-1999 school year, Miami-Dade County Schools implemented mandatory random weapons searches in schools, whereas Broward County did not. Using a difference-in-differences estimation strategy, the results indicate that the searches reduced the likelihood that students brought weapons to school and reduced incidences of being offered illegal drugs at school in Miami. Moreover, students in Miami were less likely to report skipping school due to safety concerns following the introduction of the searches
