C’est votre gros problème : vous n’avez pas la patience de vous informer. Vous ne cessez de le répéter : "je n’ai pas la patience"... de travailler, de lire, de réfléchir. Du coup, vous passez votre vie à répéter les mêmes erreurs, jamais vérifiées. Comme vous dites, ça frôle la débilité... votre comportement, que l’on pourrait qualifier d’ignorance volontaire.

Il n’y a jamais eu de "balle magique" (sa trajectoire était rectiligne). C’est une pure intox. Je cite Bugliosi, qui explique la mécanique conspirationniste : des prémisses fausses et, par conséquent, des raisonnements fallacieux :

Lindley : You explain how the “Magic Bullet” wounded both JFK and Governor Connally.

Bugliosi : These conspiracy theorists not only lie when they’re controverting documentary evidence, but they also lie when there’s actual photographic evidence disputing what they’re doing. In their sketches, they place governor Connally [directly] in front of President Kennedy in the presidential limousine, and then they argue that a bullet coming from the right rear, passing through Kennedy, from right to left, would have had to make a right turn in midair and then a left turn to hit Connally.

If you start with an erroneous premise, everything that follows makes a heck of a lot of sense. The only problem is that it is wrong. There’s no question that Connally was not seated directly in front of Kennedy in the presidential limousine. He was seated to his left front. I have a photograph in Reclaiming History showing exactly where they were seated, and right along side of it I show sketches that they put in conspiracy books, [with Connally] right in front and the bullet is making a right turn and a left turn. But he was seated to [JFK’s] left front in a jump seat a half-foot in so the orientation of Connally’s body vis a vis Kennedy’s was such that a bullet passing on a straight line, through Kennedy, would have no where else to go, except to hit Governor Connally.
