The safety of a society, by way of getting all necessary arrangements for unfailing protection and preservation of individual's liberty and rights relating to his/her person and property, is the fundamental goal of criminal justice, and for this reason it has been regarded as an indispensable system of peace and order. In achieving this goal, criminal justice system uses multi-pronged processes—investigation prosecution, and adjudication which exist as independent jurisdictions but function as one 'integrated system.' The final outcome appears in one of the two forms—i.e. either the suspect is declared 'guilty' or he/she is 'innocent'. Criminal justice system by application of this process, reaching to the state of conviction and making the offender subjected to a system of punishment, functions as an effective instrument of 'deterring potential offenders' , thus guaranteeing an effective system of preventing transgression in person or property of one individual by other individual.
