The Algiers Motel Incident occurred in Detroit, Michigan, United States, during the night of July 25–26, 1967 during the racially charged 12th Street Riot.  At the Algiers Motel, approximately one mile east of where the riots began, three teenage civilians, all of them black, were beaten and killed by police.  Nine others—two white females and seven black males—were badly beaten and humiliated by members of a riot task force composed of the Detroit Police Department, the Michigan State Police, and the Michigan Army National Guard, and a private security guard.

A private security company is a business corporation, which provides armed and unarmed security services and expertise to private and public clients.  Private security companies are defined by the U.S. Bureau of Labor Statistics as companies primarily engaged in providing guard and patrol services, such as bodyguard, guard dog, parking security and security guard services.  Many of them will even provide advanced special operations services if the client demands it.  Examples of services provided by these companies include the prevention of unauthorized activity or entry, traffic regulation, access control, and fire and theft prevention and detection.  These services can be broadly described as the protection of personnel and/or assets.  Other security services such as roving patrol, bodyguard, and guard dog services are also included, but are a very small portion of the industry.

The private security industry in South Africa is an industry providing guarding, monitoring, armed reaction, escorting, investigating and other security-related services to private individuals and companies in the country.  Over the years there has been tremendous growth in the private security industry, not only in South Africa, but also in the rest of the world.  The private security industry in South Africa is among the largest in the world, with over 9,000 registered companies, 450,000 registered active private security guards and a further 1.5 million qualified (but inactive) guards; many times the available personnel than the combined South African police and army.  Studies have shown that South Africa had 2.57 private security personnel for every police employee.  This is attributed by some to the country's relatively high levels of crime to a lack of public funds from Parliament towards the South African Police Service (SAPS) or to an increasing trend in many countries towards government outsourcing of certain security functions.  Others have suggested the number of high-wealth individuals in South Africa in comparison with the rest of Africa has led to the growth of the industry.

It was formed by the NYPD commissioner and four former NYPD chiefs who had become leaders in the private security community.  Part of its work involved overcoming the mutual distrust between public police and private security; the former typically looked upon the latter as being ill-trained and uneducated, while the latter resented being treated as less than professional enforcement officers.
