english: The one which was tapping phone calls was completely separated from the one which controlled the letters, for good reasons, because if one agent quit the Stasi, his knowledge was very small.
non_english: Odsek za prisluškivanje telefona bio je potpuno odvojen od odseka koji je proveravao pisma, s dobrim razlogom, jer ukoliko bi agent napustio Štazi, njegovo znanje je bilo veoma malo.
