Quoting from p.21 in my book "Capitalism: Servant or Master?",
"Private security guards have outnumbered government police officers since the 1980s. Coordination between private and official agencies often ovelap and the private agencies now perform work previously assigned to official agencies.(2.4) Wackenhut for example has contracts to guard the Internal Revenue Service, the General Accounting Office, the Federal Reserve, Oak Ridge National Security Complex, Savannah River nuclear plant, Jet Propulsion Laboratory, even Fort Bragg, and this is not a complete list. They also have various resouces devoted to airports, ports, and specialized Global Response Teams and Executive Protection Services, etc.
Wackenhut, DynCorp, Blackwater, Triple Canopy are four of about forty-five “Private MIlitary Firms” that can be found on a “partial list”. (2.5) There are recurring reports that some members of local police forces leave their jobs to begin work with the private police forces which pay more money and have fewer regulations."
