Gathering information from convicted offenders presents both practical and ethical challenges. Practically, offenders may lie or withhold information to gain early release, glorify their crimes, or protect themselves, their families, or criminal groups. Ethically, talking about crimes could be therapeutic for some but distressing for others, and offenders have the same human rights as other research participants, including the rights to withdraw, privacy, and debriefing. The information provided could also potentially lead to distress if offenders fear it being used to convict others.
