Final answer:
Private sector security places strong emphasis on crime prevention and deterrence, aimed at changing the potential outcomes of criminal behavior to disincentivize the act.
Step-by-step explanation:
The emphasis on private sector security is largely placed on crime prevention and deterrence. Unlike public law enforcement whose duties may include to 'protect and serve,' and which has the capacity to 'arrest and detain,' the private sector's role in security tends to focus on deterrent and preventive measures. This approach aligns with broader criminal justice strategies which prioritize changing the costs, benefits, or opportunities of criminal behavior to prevent crimes from occurring.
