Sure it can if you are like some here trying to raise false dobut. They claim no one saw Oswald pull the trigger. Therefore it creates doubt he was the assassin. Using that same mislogic, no one saw Booth pull the trigger.
No one saw Oswald at all. A whole theater full of people saw Booth. Your analogy is ridiculous.
Brennan saw Oswald holding a rifle in the same manner as witnesses saw Booth but dishonest CTers argue that doesn't mean Oswald shot JFK.
Brennan didn?t identify Oswald in a lineup on 11/22, even after seeing his picture on television. He then embellished a story involving seeing a guy who would have necessarily had to have been crouched down behind boxes ?from the belt up?, and could also somehow determine how tall he was too.
Again, nothing like Booth.
