Why Hoover lied about copper residue on the curb gouge:
This is the most complex aspect of solving the mystery of the JFK assassination. Briefly, the Hoover FBI needed to squash belief in a conspiracy and at the same time protect the Secret Service’s non-reaction to what they knew was a very early first shot. They knew the bullet gouge was caused by Oswald zeroing his scope with that early first shot but to admit it would irreparably tarnish the reputation of the Secret Service. Yet to declare that the gouge was from another type of bullet would be to admit a conspiracy. Both could lead to a spike in assassination attempts and a de-stabilization of the government.
What would you do?
The FBI at first denied any curb gouge or even a mark existed. When confronted with photos in the media, Hoover insisted that it was only a “smear” and not caused by a bullet. Yet Dallas Sherriff’s Deputies Walthers and Sweatt as well as eyewitness James Tague stated that it was “a bullet mark, and freshly made.” Other than that single un-sworn letter from Hoover to Rankin, there is no hard evidence that a spectrographic analysis was ever conducted.
Hoover did what he honestly believed was best for the country. You might have done the same thing. I would have.
