Good evening Daniel, good response. Private security and public policing are similar as well as different in many ways. Base on knowledge and training they both provide their officers skills they need to keep the public safe. When it comes down to the administrative aspect, they both are different. Like you stated in your response, private security are hired by private businesses/organization. Their duty is to provide security services to the business/company that hire them and also keep the compnay/business assets safe. Private security have a specific area that they work as compare to public police officer who primary juridiction is the entire city they work for. Private security can hire both full and part time employee, public police agencies
