Mr. Eisenberg. How would you evaluate the possibility of another person having simulated the handwriting of Lee Harvey Oswald in these questioned documents?
Mr. Cadigan. I don't think there is any possibility.
Mr. Eisenberg. On what do you base that?
Mr. Cadigan. I base that on 23 years experience and judgment and the examination of the documents and the various writings involved in this instance.
Mr. Eisenberg. And do I understand that if that had happened, the person would have left evidence behind which you would have detected?
Mr. Cadigan. In my opinion, yes.
Mr. Eisenberg. And that would be in what form?
Mr. Cadigan. It would be in many forms. Failure to incorporate into the writings things that should be there, and including in the writings things that are not in Oswald's writing, differences in slant, spacing, proportions of letters, both to other letters and proportions of letters within themselves, the adoption of the various variations that you find in the known writings. When the amount of writing approaches the amount involved here, there is a large, a relatively large volume of questioned writings. The possibilities of successful or undetectible forgery, in my opinion, are nil.
Mr. Eisenberg. Mr. Cadigan, I now hand you Commission Exhibit No. 1, which is a note in the Russian language in cyrillic print, and ask you whether you have examined that item?
Mr. Cadigan. Yes.
