Creative Speculation

Which limit it to two frames....1/18th of a second and not any more than that...so you are in control of the discussion and you are the one that insist that the head moved...when honestly if you look at 312 and 313 you will find it hard to say how much if at all...but no matter you got me...your conclusion dispenses with all other information and no need to look at any other frames past 313...you win I loose.
And this is the same pattern all debunks of CTs use.,,bisect it till you find some unanswerable point then claim victory.

I say the evidence shows that the bullet struck in frame 313...or just mili seconds before the shutter on the camera opened although it could have been at the same time because the shutter stays open a very short time and could record the impact and the eruption of matter...and the next frames show a definite violent movement backwards and to the left....there is no question about that....that is plane to see....and you have no explanation for it that makes any sense.

But believe what you want and for the reason you have...makes no difference to me....the vast majority of people believe it was a conspiracy because of the volume of evidence that shows it was...and most of them are not going to change that by these so called facts on two frames of the film.
