LOL! Are you really just a child? What kind of nonsense is this? I have to wonder about your level of intelligence to make such an argument. Anyway, no, slightly horizontal is nothing like being slightly pregnant. Bullet angles are not an all-or-nothing proposition. Bullets can strike at a wide range of horizontal angles, from very slight to slight to moderate to sharp. Bullets can also yaw by a wide range of degrees, from 1 degree upward. The fact that you need this explained to you says much about your credibility.
So tell us where a bullet could have been fired from which would have produced the angled entry into JBC's back.
They's be throwing snowballs in hell before I need you to explain anything to me.
The bullet that struck Connally's back must have done so at a slightly horizontal angle or while slightly yawing because the wound path through Connally was not very wide but surprisingly narrow, as Dr. Shaw explained.
Just what would have caused the bullet to yaw if it had not struck someone or something first?
Again, a bullet striking in this manner could have easily created a 1.5 x 0.8 cm entry wound, virtually identical in size to JFK's rear head entry wound (1.5 x 0.6 cm), which in turn explains the surprisingly narrow wound path through Connally's chest.
We still need an explanation for where such a bullet could have been fired from or what caused it to yaw. While you're at it, see if you can figure out why a bullet entering at that angle wouldn't have continued through to the left side of JBC's torso instead of exiting from the right side as it did.
To believe your whacky theory, we'd have to assume that your supposedly sideways-streaking bullet magically straightened out almost completely a few milliseconds after penetrating the back so that it could create a narrow wound path through Connally's chest.
I guess the concept of a tumbling bullet escapes you. The orientation of such a bullet is going to be constantly changing. The long axis of the bullet will go from parallel to the direction of travel, to perpendicular and everywhere in between.
