On the 27th of August 2011 a document appeared on cryptome.org, a whistleblower site. It was about an American cryptanalyst, Joseph Sidney Petersen, who leaked classified information to the Dutch Colonel Jacobus Verkuyl. He was sentenced to seven years in prison.
The case was ‘completed’ 56 years ago. The question is why does a site like cryptome pay attention to an old case. In what way is it still relevant to us now?

The case was a big scandal in America in the mid fifties. Betraying your country was not done, not now, not then. Maybe that's why this case is still relevant today. The revive of the case may also have to do with the need to complete the case. Though Petersen had been convicted, there are still a lot of gaps in the story, literally.
The reason why there are gaps is because of the classified information, which may or may not be harmful to people when unveiled, and the supervision of the National Security Agency (N.S.A.).
Still, there’s a law that says that documents more than 25 years old are to be made public, because the American people have a right to know how their tax money is spent. Because of this, there are people in the N.S.A. who edit documents before they go public. Classified information remains secret; that’s why these public documents have gaps in it.
Together with the N.S.A., Cees Wiebes, who writes about espionage and relationships between countries in times of war, knows what the gaps contain. Wiebes wrote a publication about Petersen’s case called operation: ‘Piet’ with the information he had access to.

Nowadays a lot of people don’t have access to this classified information to complete this story. What I wanted to show is how you still can make this story more complete by doing research on-line and make comparisons in that new found material to discover new connections. First I deconstructed the document that appeared on cryptome.org and made a time line focusing on Petersen. Then I searched for the people that surrounded Petersen during the case. This publication is about on-line found material about the people surrounding Petersen to attempt to complete Petersen’s case.
