Did Clemon Johnson see Smoke from a Rifle on the Grassy Knoll?

Did Clemon Johnson see Smoke from a Rifle on the Grassy Knoll?

Another one of Mark Lane's witnesses to support his theory that a gunman was firing from the grassy knoll was Clemon Johnson: (page 40 of Rush to Judgment)

Clemon E. Johnson told FBI agents that he had observed 'white smoke.'

Here is his FBI report:



Johnson tells the FBI that, at the time, "he did not know that it was shots and he could not say how many shots he heard."  But, for some strange reason, Mark Lane does not quote the last line:

Mr. Johnson stated that white smoke was observed near the pavillion, but he felt that this smoke came from a motorcycle abandoned near the spot by a Dallas policeman.
Here is what Clemon Johnson told Larry Sneed for his book, No More Silence: An Oral History of the Assassination of President Kennedy: (page 81 in the Kindle edition)

I didn’t have any idea where the shots came from, not even a guess. I was looking down at the President as they came through, and I didn’t hardly look up till he was gone. I wasn’t looking up at those bushes. I did see smoke, lots of puffs of smoke, but I was of the opinion that the smoke was coming out of those motorcycles. The smoke was coming up off the ground out where the motorcycles were, not on the grassy knoll. A lot of them said they saw smoke come out of the grassy knoll, but I didn’t. Maybe it’s because they were looking that way, and I was looking down on the car. But the smoke cleared up pretty quick after all the cars and motorcycles left. I’ve always thought the smoke came from those motorcycles.
Of course, Mark Lane leaves out of his book the fact that Mr. Johnson thought the smoke was from motorcycles.
