Mr. Latona, one further question on this subject. When you testify in court, do you frequently testify on the basis of the photographs rather than the original object?
Mr. Latona. If the originals are available, I would prefer that they be brought into court. If they are not, then photographs are used—plus the original negative of the latent prints which were photographed.
Mr. Eisenberg. Now, Mr. Latona, I hand you Commission Exhibit 139 which, for the record, consists of the rifle found on the sixth floor of the TSBD building, and which was identified yesterday as the rifle—and the day before yesterday—as the rifle which fired the fatal bullets, and I ask you whether you are familiar with this weapon?
Mr. Latona. Yes; I am.
Mr. Eisenberg. And did you examine this weapon to test—did you examine this weapon to determine whether there were any identifiable latent fingerprints on it?
Mr. Latona. I examined the weapon to determine whether there were any identifiable latent prints on the weapon.
Mr. Eisenberg. When did you receive the weapon?
Mr. Latona. On the morning of November 23, 1963.
Mr. Eisenberg. And when did you proceed to make your examination?
Mr. Latona. I proceeded to make my examination that same day that I received it.
