Mr. EISENBERG. Now when you made these identifications--or, I should say, when you received the photographs and when you made the identifications, did you have any knowledge of any kind as to how many, if any, prints of Oswald's were found among the many impressions which were given to you? Mr. MANDELLA. I had no idea, sir. Mr. EISENBERG. Were you aware in any way of the conclusions of any other body concerning these impressions? Mr. MANDELLA. I knew nothing about any examination by anyone. Mr. EISENBERG. At an unofficial level, had you seen anything in the newspapers which would indicate any information on these? Mr. MANDELLA. In the newspaper several months ago there was reference to a--I don't even recall whether it was fingerprints or palmprints or both but there was some reference in the newspaper I had seen, and that is all. Mr. EISENBERG. That is all you recall about it? Mr. MANDELLA. That is all I recall. Mr. EISENBERG. Did you pay any attention to that in making your identifications? Mr. MANDELLA. No; it didn't affect me at all, nothing to do with the identifications. Mr. EISENBERG. What is your general attitude toward items you see like this in the newspapers, by the way? Mr. MANDELLA. In the newspapers? It doesn't mean a thing. Attitude relative to fingerprints? Mr. EISENBERG. I am trying to determine how far this might influence you in your evaluation, and I wonder as a police officer what your opinion is when you read accounts in newspapers of evidence in crimes. Mr. MANDELLA. No; it doesn't affect me other than for general information purposes. Mr. EISENBERG. Did I transmit to you any information whatsoever concerning these prints? Mr. MANDELLA. You did not, other than giving me the photographs. Mr. EISENBERG. Did I tell you that any of these prints might be Lee Harvey Oswald's? Mr. MANDELLA. You made no indication as to that it could have been his. Mr. EISENBERG. Do you know now, apart from your own identification, have you acquired any information at this point, subsequent to your identification but prior to your appearance here, as to these prints, other than your own identifications? Mr. MANDELLA. I have no knowledge as to what has been done with these prints at all by anyone. Mr. EISENBERG. Are you absolutely sure as to each of these identifications, Mr. Mandella? Mr. MANDELLA. I am positive. Mr. EISENBERG. Mr. Mandella, are you familiar with the contention of some persons that 12 points are needed for identification of finger or palm prints? Mr. MANDELLA. No I am not, no. Positive identifications are effected by the expert himself; 12 points are not necessary. A sufficient amount determined by the expert is the important factor. Mr. DULLES. About how many? Have you any test as to how many points? Mr. MANDELLA. I can't give a definite number, but I'd say in generalities five or six or seven points certainly should be enough, depending on their uniqueness and frequency.
