Mr. Chairman, I would like to emphasize that, on certain occasions, it is impossible to know whether the information has been obtained by torture. On other occasions, however, it's obvious from the nature of the information. For example, we can know whether information has been obtained through technical intercepts or other investigation techniques, by shadowing, or whether it's information that was already in the files of the service in question. When there are any doubts, we can also try to find out a little more about the manner in which the information was obtained, by going back to the service and asking some questions. However, it may be impossible at times to determine with any certainty whether the information was obtained by torture.
