This study reports the findings of a randomized controlled trial (RCT) involving more than 400 police officers and the use of body-worn cameras (BWC) in the Las Vegas Metropolitan Police Department (LVMPD). Officers were surveyed before and after the trial, and a random sample was interviewed to assess their level of comfort with technology, perceptions of self, civilians, other officers, and the use of BWCs. Information was gathered during ride-alongs with BWC officers and from a review of BWC videos. The collection includes 2 SPSS data files, 4 Excel data files, and 2 files containing aggregated treatment groups and rank-and-treatment groups, in Stata, Excel, and CSV format:
