What point?
They have measured every inch of Dealey Plaza, done painstaking computer recreations, and we are supposed to take your opinion based on a still photo?
The first shot happened well before the Stemmons sign. Willis testified he took a photo reacting to a pop, you can see him in the Zapruder film and the photo he took shows the limo's location at the time of the first shot. You can also see Connally react to the first shot as his head jerks from left to right and he starts looking over his shoulder before they go behind the sign. This shot grazed the traffic signal and was deflected causing the Tague injury.
The second shot hit Kennedy in the upper back, came out his throat, started to yaw...as the keyhole wound in Connally's armpit proves. In the recreations the bullets time after time going trough ballistic gel would start turning sideways on the exit. Kennedy's jacket had bullet wipe, something that a fired bullet will leave on first contact with a target. A "bullet wipe" is a gray or black ring around an entrance bullet hole. The ring is formed by and contains bullet lubricant, byproducts of propellant, traces of bullet metal, and residue in the gun barrel from previous use. Connally's jacket had no bullet wipe. So you have the back of Kennedy's jacket showing bullet wipe meaning a shot from behind. You have a bullet that will turn after passing through a person, as the ballistic tests show. You have Connally's jacket with no bullet wipe, meaning that hole was not the first thing the bullet contacted. You also have a hole in the jacket and wound in Connally's armpit that were the same size as a CE 399 if it were going sideways. This sideways motion would also slow the bullet and make it less likely to be damaged as it passed through his rib and wrist. A bullet traveling sideways would not receive damage to the tip, but would be bent...just like CE 399 was.
Here is the final nail in your point. Those measurements and computer recreations of Dealey Plaza, the location of the limo based on the Zapruder film, all line up perfectly from Connally's thigh, backwards through his wrist, chest, back, Kennedy's throat, back and right to the 6th floor window of the TSBD. Lead fragments that matched CE 399 were removed from Connally's wrist meaning that a bullet that matched Oswald's rifle caused that wound. A wound that was made by a bullet traveling backwards so it had to pass through something first, so it clearly caused his chest wound first, so that means it also caused the wound in his back that was of a bullet going sideways that did not leave any bullet wipe...so what did CE 399 hit before it hit Connally?
