Often, enforcement officials' access to information regarding individuals involved in illegal organ transplants is hindered by medical confidentiality regulations. Without the ability to review medical records and histories to build an effective case against perpetrators, officials cannot fully enforce organ trade laws.[64] Many critics state that in order to prohibit illegal organ trading effectively, criminal justice agencies must collaborate with medical authorities to strengthen knowledge and enforcement of organ trade laws. Critics also support other criminal justice actions to meet this goal, such as prioritizing organ trafficking issues among local legislative bodies; multidisciplinary collaboration in cross-border offenses; and further police training in dealing with organ trafficking crimes.[43]
