Речь идёт о техниках допроса

Не совсем понятно:

Лицо, исполняющее роль информатора, может быть выведено через заднюю дверь в начале данных процедур….

или

Лицо, исполняющее роль информатора, может быть выведено обратно через дверь, которую он пересёк в начале процесса….

Или как-то иначе?

The Witness
If others have accused the interrogatee of spying for a hostile service or of other activity which he denies, there is a temptation to confront the recalcitrant source with his accuser or accusers. But a quick confrontation has two weaknesses: it is likely to intensify the stubbornness of denials, and it spoils the chance to use more subtle methods.

One of these is to place the interrogatee in an outer office and escort past him, and into the inner office, an accuser whom he knows personally or, in fact, any person --even one who is friendly to the source and uncooperative with the interrogators - who is believed to know something about whatever the interrogatee is concealing. It is also essential that the interrogatee know or suspect that the witness may be in possession of the incriminating information. The witness is whisked past the interrogatee; the two are not allowed to speak to each other. A guard and a stenographer remain in the outer office with the interrogatee. After about an hour the interrogator who has been questioning the interrogatee in past sessions opens the door and asks the stenographer to come in, with steno pad and pencils. After a time she re-emerges and types material from her pad, making several carbons. She pauses, points at the interrogatee, and asks the guard how his name is spelled. She may also ask the interrogatee directly for the proper spelling of a street, a prison, the name of a Communist intelligence officer, or any other factor closely linked to the activity of which he is accused. She takes her completed work into the inner office, comes back out, and telephones a request that someone come up to act as legal witness. Another man appears and enters the inner office. The person cast in the informer's role may have been let out a back door at the beginning of these proceedings; or if cooperative, he may continue his role. In either event, a couple of interrogators, with or without the "informer", now emerge from the inner office. In contrast to their earlier demeanor, they are now relaxed and smiling. The interrogator in charge says to the guard, "O.K., Tom, take him back. We don't need him any more. " Even if the interrogatee now insists on telling his side of the story, he is told to relax, because the interrogator will get around to him tomorrow or the next day….

Буду признательна за информационную поддержку.
