We all know that Police in Pakistan is corrupt. If they were well trained then maybe half of terrorism wouldn't exist. Its sounds a but weird but the highway police that we have, the one that is privatized is quite good.
Here are some countries that are following this kind of system:
Examples
United States
In South Carolina, all Security Officers have the same authority and power to make an arrest as Sheriff's Deputies.[8] Spring Valley HOA in Columbia, SC is a good example of this. Private Officers respond to calls for service, make arrests and use blue lights[9] and traffic radar. They are Law Enforcement under state law, case law and AGs opinion, and are authorized by the state to issue Uniform Traffic Tickets to violators.[10] Security Officers in some cases are also considered Police Officers.
In Boston, Massachusetts, more than 100 housing projects and low-income apartment buildings are patrolled by private security. One firm, Naratoone Security Corporation, fields 122 traditional security officers in those locations, as well as 43 special police officers, who are armed and licensed by the Boston Police Department and have limited arrest powers.
South Africa
Main article: Private security industry in South Africa
An increasing number of South Africans are using private security companies to protect themselves and their assets. The broad private security industry is employing over 200,000 security guards throughout the country, of which the guarding industry is the largest, with 125,000 guards working for approximately 3,200 security companies. Many of the larger South African private security companies have expanded their operations into other countries in Southern Africa. Private security companies have even involved themselves in political conflicts that are occurring on the subcontinent. In South Africa, private companies that make use of guards are regulated by a statutory body, the Security Officers' Board. The Board polices the regulations that govern the private security industry and sets minimum training standards for security guards.[13]
