Nah, nothing wrong here, nothing at all.
While Oswald was alive:
"Our fine men in uniform, the SS, the FBI and many other government agencies have redoubled their fine efforts and were not able to find Oswald's fingerprints on that gun"
Chief Curry to press
47 hours later after Oswald was shot dead while in Police custody:
"Our fine men in uniform, the SS, the FBI and many other government agencies have redoubled their fine efforts and were able to find Oswald's fingerprints on that gun. In that 47 hours of super sleuthing, they all must have missed some tiny area to check I imagine, now no more questions, we're very busy here"
Chief Curry to press
Seems Curry didn't know a lot of things about the evidence...
Jesse Curry WC Testimony
http://mcadams.posc.mu.edu/russ/testimony/curry1.htm(...)
Representative FORD - What evidence did you have at that point?
Mr. CURRY -
I couldn't tell you all the evidence. I think Captain Fritz can tell you better than I. Captain Fritz Just told me on Friday afternoon he said, "We have sufficient evidence to file a case on Oswald for the murder of Tippit." Later on that night, somewhere around midnight, I believe,
he told me, he said, "We now have sufficient evidence to file on Lee Harvey Oswald for the assassination of President Kennedy."
He told me he had talked it over with Henry Wade and with the assistant district attorney and
they agreed we had enough evidence to file a case, and a decision was made then to file the case, which we did.
Representative FORD - At that time you had the rifle, did you not?
Mr. CURRY - Yes, sir.
Representative FORD - Who made the original identification of the rifle, the kind of rifle that it was?
Mr. CURRY - I don't know, sir.
Representative FORD - It was reported that the original identification was a 7.65 Mauser. Are those reports true or untrue?
Mr. CURRY - I wouldn't know, sir.Representative FORD - You don't know?
Mr. CURRY - I don't know.
Representative FORD - Do you know when it was finally determined that it was not a 7.65 Mauser?
Mr. CURRY - No, sir; I don't know that.
Mr. MCCLOY - As far as I know there was no police report that it was a 7.65 rifle.
(Discussion off the record.)
