  Even when prosecutions do not threaten political stability and manage to stay true to the principles of the rule of law, they can still come into conflict with the desire to create a robust, comprehensive historical record. When trials are used as the primary mechanism of transitional justice, their very subjection to the rules of evidence means that some important information (namely testimony that does not pertain to specific indictments, or evidence obtained without full due process etc.) will be excluded from the record. This limitation has prompted some scholars to argue that truth commissions are preferable to war crime trials in this respect: since such commissions are not subject to the rules of evidence, they are able to collect more information, expose a more comprehensive picture of past injustices and to include a greater emphasis on the role of institutional and commercial actors indirectly involved in  supporting injustices.[5]
