A large number of people feel that private security is reserved for only celebrities or individuals of high net worth. What most people don’t know is that private security actually outnumbers the police in most countries worldwide. You just may not notice them as they can be seen patrolling schools, conducting screenings at airports and of course guarding high profile clients. Currently the number of private security officers is around 20 million and the industry itself is worth nearly $180 billion. Specifically, in the United States there are nearly 1.1 million security guards and only 660,000 police officers.
