For the benefit of the newbies...
Josiah Thompson had dug some article out of the NY Sunday news [which NY news ?] anyway, Steve Barber located that article and here it is... http://mcadams.posc.mu.edu/hargis.htm
One thing seems evident...the splatter went to the left of the car and into the policeman.
The majority of the head matter flew forward and all over the car, the Connally's, Kellerman, Greer. According to Robert Frazier, there was blood, bits of bone, and brain tissue scattered all over the interior, the seats, the windshield, (both sides) sun visors (both sides) both side rails, the hood of the car and trunk lid. All of that matter had more volume to it than the minute particles( mist) that landed on Hargis and Martin, and neither Hargis or Martin said anything about being struck with "force" by the stuff that landed on them. Martin didn't witness the fatal shot and didn't even know he had matter on his person.
----------
Mr. BALL. You had a white helmet on?
Mr. MARTIN. Yes.
Mr. BALL. Did you notice any stains on your helmet?
Mr. MARTIN. Yes, sir; during the process of working traffic there, I noticed that there were blood stains on the windshield on my motor and then I pulled off my helmet and I noticed there were blood stains on the left side of my helmet.
Mr. BALL. To give a more accurate description of the left side, could you tell us about where it started with reference to the forehead?
Mr. MARTIN. It was just to the left - of what would be the center of my forehead - approximately halfway, about a quarter of the helmet had spots of blood on it.
Mr. BALL. And were there any other spots of any other material on the helmet there besides blood?
Mr. MARTIN. Yes, sir; there was other matter that looked like pieces of flesh.
Mr. BALL. What about your uniform?
Mr. MARTIN. There was blood and matter on my left shoulder of my uniform.
Mr. BALL. You pointed to a place in front of your shoulder, about the clavicle region?
Mr. MARTIN. Yes, sir.
Mr. BALL. Is that about where it was?
Mr. MARTIN. Yes.
Mr. BALL. On the front of your uniform and not on the side?
Mr. MARTIN. No, sir.
Mr. BALL. That would be left, was it?
Mr. MARTIN. Yes; on the left side.
Mr. BALL. And just below the level of the shoulder?
Mr. MARTIN. Yes, sir.
Mr. BALL. And what spots were there?
Mr. MARTIN. They were blood spots and other matter.
Mr. BALL. And what did you notice on your windshield?
Mr. MARTIN. There was blood and other matter on my windshield and also on the motor.
Mr. BALL. Was the blood noticeable - were there large splotches?
Mr. MARTIN. No; they weren't large splotches, they were small - It was not very noticeable unless you looked at it.
Mr. BALL. Was the discoloration on your helmet noticeable?
Mr. MARTIN. Not too much - no -as a matter of fact, there were other people around there and two more officers there and they never noticed it. (emphasis mine).
Mr. BALL. At that time were you with Mr. Hargis?
Mr. MARTIN. No, sir; I don't believe that he went to the hospital with us. I believe he stopped there at the scene of the shooting.
Mr. BALL. And did you ever see his helmet or his uniform or the windshield of his motorcycle?
Mr. MARTIN. No, sir - I never recall seeing him again until the next day.
Mr. BALL. Now, was this blood on the outside or the inside of your windshield?
Mr. MARTIN. It was on the outside of my windshield.
Mr. BALL. Was it on the right or left side?
Mr. MARTIN. It was on the outside of my windshield.
Mr. BALL. And what about the fender of the motorcycle?
Mr. MARTIN. It was just in the front - right on the front just above the cowling on the motorcycle.
