Hi Rob
Indeed Swanson could have meant that the identity of the Ripper was known to the top officials of the Yard, although his handwritten note leads on naturally from the text at the end of the paragraph, viz., "[printed] the creation of an enterprising London journalist. [handwritten] known to Scotland Yard head officers of CID." Since the idea of each these annotations seems to expand on Anderson's printed word with more information from his own knowledge, I do believe he is saying the journalist responsible for Dear Boss was known to the top officers of the Yard. Case Closed.
