Why Evidence Obtained From Torture Should Never Be Admissible

JB

At the same time you wish to deter the use of torture in every other circumstance, because you are worried about descending down the slippery slope to situations where a great peril is not imminent, or where the information elicited by torture is not necessary to prevent this great peril but is merely helpful to advance national security or other important interests.

The best way to achieve this set of goals would be not to carve out a legal exception for torture in emergencies but rather to impose a total ban. If the situation is so dire that torture is absolutely necessary to save a large number of people, illegality will not be a deterrent. Government officials will still commit torture. Then, after the fact, legal decisionmakers can determine whether their actions should be excused or pardoned.

Even if you excuse or pardon torture after the fact, however, you should not make evidence obtained by torture admissible in a subsequent military tribunal or criminal prosecution. If the torture was necessary to prevent an imminent and grave peril, the information should be used for that purpose, and that purpose alone. Otherwise you will indeed descend down the slippery slope, because you have created incentives for government officials to torture in order to elicit information for the purpose of assisting military or criminal prosecutions.

If this line of reasoning is roughly correct, then Congress is making a terrible mistake when it proposes to ban torture (and cruel, inhuman, and degrading treatment) while simultaneously allowing evidence obtained through such methods to be admissible in military tribunals that determine the status of persons held at Guantanamo Bay. The obvious reason for the proposed rule is that the CIA has in fact engaged in a good deal of cruel, inhuman, and degrading treatment to secure information, or it has shipped people off to countries where they have been subjected to these methods; the information has already been elicited and the government wants to use it.

Congress should resist this line of argument. We should not allow ourselves to use the fruits of torture (or CID treatment) even where the torture (or CID treatment) has already occurred. Otherwise we give ourselves incentives to employ these methods where they are not absolutely necessary. The correct rule is a total ban on torture and cruel, inhuman and degrading treatment and a total ban on admissibility of evidence produced by these methods. As suggested above, this rule will not in fact mean that the government will never torture anyone. But it will help deter government from practicing torture in all the situations in which it should be deterred.
