Victims of trafficking may have been prevented from taking part in religious services Turing their period of victimization. This can have a serious effect on the psychological well-being of those victims for whom religion is an important part of their lives.
In some cases religion has been used by traffickers to control victims. A commonly encountered example is that of African traditional religions and their derivatives that are found throughout parts of the Americas.
All of these present both challenges and opportunities for investigators. The attitude of the investigator is the key to meeting those challenges and maximizing opportunities. Specifically, you should have an open mind and approach this subject without prejudice.
