There are many reasons of why security guards are essential. They help protect businesses, schools, banks, and other important places. Not only do they protect places, but they also protect people. Many famous people will hire security guards known as body guards or a security guard company to protect them. When a bank is bringing in money to its building, security guards move the money and take it into the bank. If these people did not protect the money the entire way, then there would be more robberies, thus these guards act as a deterrent for robbers.
