In order to reform and improve the relationship between the police and the procurator,it has been asserted for many years that the system of integrating the police and the procurator,under which the procuratorate leads the police,should be established in China.However,it still has not been resolved.For ages it has been ignored that integrating the police and procurator in foreign countries is essentially based on the separation of powers and the litigious idea on doctrine of function and power.This system is not conformed with the primary purpose of the criminal justice system reform in China,which will result in misunderstanding the idea and ignoring the specialty of the political and law systems.Therefore,if the abuse is discovered only in the system of integrating the police and procurator,the outlet will never be found.The point is that,the reform should depend upon the change and the discrimination of the ideology.By only cloning the system of other countries,the inner relations won't be seen.
