So what you apparently believe is that your conspirators just decided to plant a bullet that precisely fits the wounds
What exactly makes you so sure that the bullet now in evidence as CE399 is the one that was found (and thus - according to you - planted) at Parkland Hospital?
Don't confuse conspirators with lone gunman. Conspirators wouldn't be looking for the magic bullet which entered and exited bodies 7 times and came out on a stretcher! We would say that is impossible! After reading the reports on the magic bullet, it should have been found and removed from Connally's leg if true - it should have been found on the operating table! If this were not the case, it would have been a nasty bruise to his leg, non- penetrating and then ending up rolling on the stretcher where it was assumed to be found later. Which way do you want it? That is the path of the magic bullet the WC reported! I mean really! The doctor's didn't remove bullet from the leg? If it is a 4th bullet, no way one gunman could have done that with his bolt action carcano!
Years later, when Connally died, some wanted to find some of these supposed remaining traces of lead deposited in his leg - frangible? That examination (biopsy) was refused and not allowed after he died. I for one, certainly would have hoped that there would have been pictures confirming that he actually had some scarring from the various operations he underwent to SAVE his life - must have had scars all over including wrist, abdomen and leg! His wife seemed to think he had a protruding chest injury as big as a baseball after pulverizing the one rib they removed. Even if an unobtrusive x-ray was taken of the cadaver it could have proved a missing rib. A total lie she spun.
He can be seen sitting in the corner behind the post behind driver Greer riding to the hospital in the Zapruder film. She was head down at JFK's feet! Look at her story again and review the Zapruder film. (I wonder if he ever had a picture taken with him sitting on a yacht years later in a bathing suit, perhaps with Lyndon Johnson.)
The stretcher bullet certainly wasn't a frangible bullet like that supposedly to have hit JFK in Z312 where its explosion would ended its path right there totally in the brain matter and skull -judging by the spray. If a similar bullet would have been used and hit Connally, it would have done the same in the chest cavity when it struck a rib and pulverized it and likely would have ended in his death. It would have tore a major hole and he wouldn't have been able to give a really good stump speech from his hospital bed less than 5 days later.
Again, as conspirators there is a mixing of different bullets by the lone shooter if you want to believe the evidence presented- very unlikely! In addition, the LN'ers called the first shot hitting the pavement and curb, the one used to check the wind and sight in his scope so he could be more accurate with the final two! I really doubt that! If you can't believe the WC report with their hypothesis put forward, then there was a conspiracy to murder the President and install a New POTUS. Very simple! With more than one gunman present, it confirms this and a cover up took place in order to hide the truth. Failure to admit and proceed with a real investigation confirms this and is why it was all kept internal and covered.
Remember the Manhattan Project? Thousands worked on it and it remained a secret! This was no different. A modern day example of the FBI and Mueller working over Trump and his election win is similar. Pretty hard to uncover anything when the DOJ and FBI heads work in each others shadows and resist any investigation by an independent inquiry of them! It is all a matter of national security, even more so if this high level of corruption where to ever be "unearthed" and brought to the light.
