Are Security Companies Private Armies

Security companies have just mushroomed in South Africa, and sadly many stupid people out there have blamed the increase in the number of security companies in South Africa on the new government, saying that because of the corruption and overspending on personal expenses, there is no money left in the national coffers to adequately provide security for the people of south Africa. These statements are not just stupid but they are also inflammatory.
 
The reason the wealthy of south Africa are spending so much money on private security companies is because where the previous government only had to concern themselves with protecting and serving ten per cent of the people, of South Africa, the current administration has set itself the goal of trying to spread to resources of South Africa among all the people. So while the police are looking after the poorer areas in has been left, to large degree, to the security companies to police the burbs.  
The security companies do not have any real powers, so they are forced to work very closely with the police. This in itself is a very good thing because most of the staff  of these security companies are people, who have been rejected by the police service for various reasons and one does not have to be a cynic to realize that the South African police service does not have the highest standards. This trend in dropping the entry level standards to the police service is a global trend.
 
Before, if you wished to join the police you had to be at least six foot tall. Some liberal politician decided that this was discriminatory and the standards were dropped all around the world. So when this security staffs that are in the employ of the security companies have been rejected by the police, one does get a bit concerned about the stability of the security company staff.
 
Are they psychopaths waiting for a chance to draw their weapons and start blazing away? This why people, are growing more nervous about the number of security companies that have sprung up in recent years, in the better parts of South Africa.
