We have several objectives in conducting these kinds of investigations. The first is to collect the forensic evidence in the hopes that eventually some justice can serve the needs such as we did in the junta trial in Argentina. That doesn't often happen, unfortunately, because, very often these people get amnesty in one form or another. But we still have that obligation to collect the forensic evidence and write it up so that, even many years down the road it can be presented in court. Another reason we do this is that even though justice is not always served, at least it puts it on the historical record that these kinds of crimes occurred. And that prevents the revisionists, who are always out there, from coming along 10 or 20 years later and saying, "You know, these things really didn't happen." A third objective is, of course, we have the obligation, after we have examined the bones, to return them, when possible, to their families so that they can be memorialized as they wish.
