09/10/69: Cable (Withheld Acting): "CARAVEL (former Abwehr and SS officer, Paul Dickopf) would definitely draw undue attention to (REDACTION) by asking one of his men to undertake investigation suggested para 2 ref. CARAVEL would be hard pressed as Chief of CAMEN (West German Federal Criminal Police - Bundeskriminalamt, BKA) to find reason why his organization would be interested finding (REDACTION) if (REDACTION) willing to surface German investigative interest in (REDACTION) could use trusted, but not recruited, liaison contacts in CAWHISPER or LfV Wiesbaden for investigation without having to reveal that (REDACTION) advise."

09/25/69: Dispatch from Chief, European Division to Chief of Base, Berlin (Info: COS, Germany): Subject: CALL/INTEL NPD Activities: "1. We are very pleased with the quality of the information on the NPD which has now been made available through CATERROR. It is particularly useful during this pre-election period, but we also appreciate not having to wait 6 to 8 weeks for CAWHISPER to digest the material and pass it on. 2. After looking over the Reference, we are inclined to stick with the requirements mentioned in DIRECTOR 39264 for items worthy of intel dissemination. In this context Bonn State Department Telegram 12253 dated 17 September quotes Foreign Minister Brandt as saying that there has been evidence that the East Germans, undoubtedly with Soviet approval, had given financial support to von Thadden. While we are inclined to think that Brandt's comment may be wishful thinking, evidence of East German financing for the NPD would be of great interest and utility...(Signature) Harriet G.
