Court trials cannot: prosecute the dead, secure direct testimony from the dead, or repair damages done to the lives of the dead; truly match punishments to crimes when the crime consists of the murder of many victims; put institutions and systems on trial; within usual rules against self-incrimination and torture, compel perpetrators to confess; summon classes of offenders newly tagged as such without engaging in the ambiguities of ex post facto prosecution — an ambiguity abolishable by legislative grants of general impunity; avoid, in most societies, the skewing influence of money and power on the effectiveness of prosecution and defence; always implement distinction between retribution and vengeance, especially in response to public demand for the latter; guarantee 'closure' or satisfaction among victims that justice has been done once a perpetrator has been punished, a problem further exacerbated by the traditional western judicial system which largely keeps victims on the margins of the whole process; always avoid adversarial abuse of plaintiffs, defendants, and witnesses; avoid scapegoating, especially in trials of leaders who required large constituencies for carrying out their crimes; or escape from the danger, inherent in the adversarial trial system, that the courtroom will become a playing field in which the most skilled, rather than the most truthful, side will win.
