The study suggests that hierarchical environments can negatively impact an individual's feeling of responsibility for their actions.
A new study found that schools with increased law enforcement officer presence experienced higher crime rates and more student exclusions. The research, conducted by the University of Maryland and Westat, suggests that increasing SRO staffing levels does not improve school safety and may even exacerbate issues.
