No, actually it doesn't. Both the WC and HSCA concluded that Lee Harvey Oswald shot and killed JFK. On that they agree. The WC "
found no evidence that either Lee Harvey Oswald or Jack Ruby was part of any conspiracy, domestic or foreign, to assassinate President Kennedy" which, as I said, is not the same as saying there was
no conspiracy.
And how does the HSCA finding of a probable conspiracy (based on evidence that was later discredited) to kill JFK contradict it's other conclusions? I notice you didn't bold the last part of paragraph B3.
The "other gunman" being the Grassy Knoll shooter.
So the WC and the HSCA
agreed on the following points: LHO shot and killed JFK. No evidence of a conspiracy involving the Soviet Government, the Cuban Government, anti-Castro Cuban groups,organized crime, the FBI, CIA, Secret Service or any other governmental body could be found.
The sole
disagreement between the WC and the HSAC was based on the
now discredited acoustic evidence.
