The purpose of this article was to improve the post-secondary vocational education curriculum for private security students by focusing on a particular applied skill -- detection of juvenile shoplifters. Educators are tasked with helping students to identify racist beliefs and reduce worldwide organisational racism in the retail industry. Consistent with this goal, 166 urban college students in the U.S. provided physical appearance, behaviour, and family characteristics comprising their stereotype of a juvenile shoplifter. After reading one of 10 shoplifting vignettes with different combinations of sex and race/ethnicity of 14-year-old shoplifter, students made decisions relevant to identification, surveillance, and consequences. Marginalised juveniles were selected the most for surveillance and given harsher, formal consequences consistent with predictions they would recidivate. The findings suggest that instructors must implement specific changes in their curriculum to guide students towards learning objective prevention measures instead of relying on discriminatory offender profiling. Instructors must teach students to pre-identify their biases and engage in critical thinking tasks to determine the best proactive detection strategies for identifying juvenile shoplifters to avoid unfair treatment of consumers from marginalised groups in their own countries.
