The need for civilian criminal investigators arises in countries that are facing financial difficulties. It gets difficult for the police to undertake all these responsibilities so civilian investigators are appointed to share this burden and reduce the load off the police staff. Instead of expanding capabilities, most cities that are facing problems like these have cut down their costs by reducing the police personnel. The police have the responsibility of protecting its citizens and lowering down the crime rate. When the police personnel is reduced, crime rates increase, and citizens start feeling less secure and show signs of dissatisfaction. Private investigators have been playing a significant role in the judicial system and assist the government agencies in safeguarding society.
