How did World War 2 influence the private security industry?

Answer 1

== == During the Second World War there was a huge increase in the need for private security guards, at war production plants to provide onsite security to prevent theft and or sabotage., and to monitor the employees for theft of company property. Manufacturing plant managers expected professionaly trained security guards, who could be trusted to be on time, stay awake and react properly in an emergency situation. The old style "night watch man " was a thing of the past. Security companies started to train their guards to be just about as good as police, but with a direct loyalty to the client's needs. Training grew to be quite comprehensive and some guards were armed while on patrol of plant properties, or when transporting the cash payroll for the workers at their plant. Some security companies had private investigators who did background checks on employees who had to have a security clearance to work in the secret production departments of a war plant.
