I am trying to come up with a suitable analogy to illustrate how stupid this is. I imagine a WWII intercept of an Enigma message being decoded and the clerk in charge then calling up the German High Command to verify the accuracy of the decoder. It is totally baffling to me that they did this in the way described without for one second thinking about how vulnerable their source was.
