Connivance is to chasing felons for goodness of society. Based on retributive policy, especially in reaction to crimes which are contrary to virtues of society, delinquency connivance has received remarkable attention especially in Islam. Like the holy verses in Quran in which you can explicitly find that probing into people’s privacy and their crime is prohibited. Connivance based on this policy is practical. The reason in which you can find permitting to apply delinquency connivance is nothing but hiding some crimes which are contradictory to the virtue of society. To put it in a nutshell, probing into crimes in which you can find vice and contradictions to the virtues of society is highly prohibited, only if probing into heinous crime is permitted by people in charge you can find the aforementioned in 43 act of our criminal procedure.
