The Warren Commission did NOT state the first shot was the one that hit Tague. That is just another falsehood by you. I previously quoted this:

"At a different location in Dealey Plaza, the evidence indicated that a bullet
fragment did hit the street. James T. Tague, who got out of his car to watch the motorcade from a position between Commerce and Main Streets near the Triple Underpass, was hit on the cheek by an object during the shooting. Within a few minutes Tague reported this to Deputy Sheriff Eddy R. Walthers, who was examining the area to see if any bullets had struck the turf. Walthers immediately started to search where Tague had been standing and located a place on the south curb of Main Street where it appeared a bullet had hit the cement. According to Tague, "There was a mark quite obviously . that was a bullet, and it was very fresh." In Tague's opinion, it was the second shot which caused the mark, since he thinks he heard the third shot after he was hit in the face. This incident appears to have been recorded in the contemporaneous report of Dallas Patrolman L. L. Hill, who radioed in around 12:40 p.m.: "I have one guy that was possibly hit by a richochet from the bullet off the concrete." Scientific examination of the mark on the south curb of Main Street by FBI experts disclosed metal smears which, "were spectrographically determined to be essentially lead with a trace of antimony."
The mark on the curb could have originated from the lead core of a bullet but the absence of copper precluded "the possibility that the mark on the curbing section was made by an unmutilated military full metal-jacketed bullet such as the bullet from Governor Connally's stretcher."
Quite simply, the Warren Commission said the fragment that hit the curb and then struck Tague was not a whole bullet, but the lead core of a bullet which had struck something hard enough to separate the core from the copper jacket. But it made no determination as to which shot did that. Most likely the head shot was the one, but it never determinated the head shot was the final one.
