That seems a plausible take, given Donahue’s lengthy dedication to research. Is there positive evidence the projectiles differed in caliber? By that I mean is there a available for inspection today a projectile known to have pierced JFK that could not possibly have been fired through Oswald’s rifle? That would go a long way in confirming Donahue’s scenario.
Thanks for taking time to clarify. Fine additions to the thread.
Not only was his research lengthy, it was very thorough. He even showed errors in other experts’ analysis.
Boiled down - the type of bullet Oswald shot was not capable of causing the massive head wound that blew his head apart. The bullet that went through the neck area was consistent with Oswald’s bullet. Donahue explains why a different type of bullet shot from behind did this, contrary to the popular accepted explanation that a shot from the front blew out the back of the skull.
Find a copy of the book, you’ll be glad you did.
