I don't accept the word of an unnamed source.
Handwriting identifications made using non-original documents are admissible in courts of law. The FBI handwriting identification expert that examined the Klein's documents was asked about using non-originals during his WC testimony:
Mr. EISENBERG. Are you able to identify the handwriting of an individual on the basis of a photograph of that handwriting?
Mr. CADIGAN. Yes.
Mr. EISENBERG. Would you make an identification, such an identification, if your only questioned document was a photograph if the photograph was sufficiently clear?
Mr. CADIGAN. If the photograph is sufficiently clear, it is adequate for the handwriting comparison.
Mr. EISENBERG. Similarly with standards, if your only standard was a photograph or your only standards were photographs?
Mr. CADIGAN. If your standards were also photographs, it is possible to make the comparison and arrive at a definite opinion.
Mr. EISENBERG. And were the photographs in this case, both the standard and the questioned documents, clear enough to form the 'basis of an opinion?
Mr. CADIGAN. Yes. I might point out that some of the known standards are original documents and not photographs.
Mr. EISENBERG. Yes; I am aware of that, but I wanted to set out on the record whether the standards which are photographs are adequate----
Mr. CADIGAN. They are adequate.
Alwyn Cole, questioned documents expert with the the U.S. Treasury Department, was also asked about it during his WC testimony:
Mr. EISENBERG. Mr. Cole, I now show you a photograph of an envelope and a purchase order. The envelope is addressed to Klein's, in Chicago, from one"A. Hidell," and the purchase order, which is included in the photograph, is order also addressed to Klein's from "A. Hidell," and I ask you whether you have examined this photograph.
Mr. COLE. I have.
Mr. EISENBERG. Mr. Chairman, may I have this admitted into evidence as Commission Exhibit 773?
The CHAIRMAN. It may be admitted.
(Commission Exhibit No. 773 was marked and received in evidence.)
Mr. EISENBERG. For the record, this photograph was produced from a roll of microfilm in the possession of Klein's, a Chicago firm which sells weapons of various types, and which sold the assassination weapon. Now, Mr. Cole, I am going to hand you a group of documents which I will identify for the record. The first is an application form to Cosmos Shipping Co., Inc., signed Lee H. Oswald, and containing handprinting and cursive writing. Have you examined that document, Mr. Cole?
Mr. COLE. Yes, sir.
.........
Mr. EISENBERG. Does a photograph in your opinion provide a sufficient standard on which to base a conclusion as to a questioned document?
Mr. COLE. Well, I believe these particular photographs are satisfactory for that purpose.
Mr. EISENBERG. Would you draw a conclusion as to the origin of a questioned document if your only standard was a photograph?
Mr. COLE. If the photographs were comparable to the photographs we have in this case; yes.
Handwriting identifications made using non-original documents are admissible in courts of law. In which court were the opinions of those FBI experts admitted?
I don't care much for the selfserving opinions of Cadigan and Cole. Of course they are going to say what they said. If they didn't their own testimony would have been rendered worthless.
Better educate yourself before you write another post, Tim. Contact some real life independent handwriting examiners and ask them. They will tell you that their conclusions are never absolute. They work with levels of probability.
This is the give away that Cadigan is full of it;
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. Even the biggest fool understands that when you have a photocopy, there is always a possibility of manipulation. For him to claim there is no such possibility only discredits everything else he said.
