Security guards are critical in maintaining safety and preventing theft in various settings. Some key points include:

• They should call the police in severe situations and avoid unnecessary risks.
• Maintain a non-confrontational approach and focus on prevention.
• They must not impersonate peace officers and should communicate their role to the public.
• Cooperate with law enforcement during emergencies and prioritize protecting the property they guard.
• Understanding employer guidelines and prioritizing responsibilities accordingly is crucial.

Private security has a long history dating back centuries, with roles evolving:

• Allan Pinkerton established one of the first private security agencies in 1850.
• Initially, private security filled gaps in law enforcement, focusing on transportation protection and crime investigation.
• Government improvements in the 20th century led to reduced reliance on private security.
• Regulations such as California's licensing requirement for private investigators began in 1915, marking industry oversight.
• Security personnel, including guards and officers, are hired to protect assets through patrolling, monitoring, and intervening to prevent criminal activities.

Security personnel must be aware of their limitations compared to peace officers and maintain professionalism and ethical communication:

• They should focus on prevention, observation, and reporting to ensure safety and security.
• For serious crimes like robbery, timely notification of law enforcement is crucial.
• Avoid escalating situations and understand legal boundaries when addressing criminal activities.
