In Jones and Newburn’ (1995) book, according to the Yellow Pages Business Database, 8259 companies might be broadly regards as provider of security services in 1994 and 1995 for the United Kingdom. This form of transparent data is not available on Chinese security services. Almost 2,281companies with roughly 180,000 personnel were regarded as provider of security services and equipment. 2547 companies with just over 100,000 personnel were regarded as provider of electronic security equipment. 864 companies 11,000 personnel provided ‘mechanical security equipment’. 767 companies with 6000 personnel provided ‘investigation services’. And 440 companies with 34,000 personnel provided ‘bailiffing and debt collection’. Jones and Newburn (1995) estimate that there were in excess of 160,000 private security personnel comparing to about 145,000 police officers in England for the year 1995 and Wales by the mid 1990s. In Button’s (2013) unpublished book, according to the 2011 Small Arms Survey Research, there were 120,000 private security personnel in the United Kingdom. On a similar note, it was observed that the United States in the second half of the 20th century became clear that security is an essential element of industrial operations. The number of security guards has grown from 200,000 in World War II to more than 1.5 million in 1990, and then it grown to 1.9 million by 2000. The development of technology in electronic and other sophisticated aids to security have provided methods for protecting persons, places, and things that were unimaginable in ancient time (Button, M. 2007).
Bayley and Shearing (1996) claimed that there was a deep distrust in government in Anglo-American culture and this might be one factor of the growth of the private security. Jones and New- burn (1998) mentioned the fiscal constraint is another factor of the growth of the private security. In Button’s (2013) unpublished book, there are several factors can be used explaining the trend of the growth of private security, including the fear from crime, the limited public police force in providing security service, the growth of private property, and the growing risk of terrorism. Many researchers have studied the private security industry in the UK and the USA; however, very limited studies were about the private security industry in Asian countries.
