It is strange how the Covid Mantra of, "Follow The Science", does Not apply to the Knott Lab Forensic SCIENCE finding that the SBT, "IS IMPOSSIBLE".
Especially given the fact that the Knott Lab analysis is the most thorough and sophisticated SBT trajectory analysis ever done. No previous analysis even comes close to matching the depth and sophistication of the Knott Lab analysis.
You can bet that if the Knott Lab analysis had concluded the SBT was possible, WC apologists would endlessly note that it is the most sophisticated, thorough SBT trajectory study ever done.
Another large nail in the SBT's coffin is the fact that JFK plainly, obviously begins to react to a hit at least 17 frames before Z224, and that when Jackie reemerges into view in Z224 she has clearly already noticed JFK's reaction. The HSCA photographic experts determined that JFK was hit at right around Z190, 34 frames before the current SBT says Connally was hit.
The Z190 hit is all the more devastating to the SBT when we consider JFK's dramatic Z226-232 reaction when he is visibly jolted forward and his hands and elbows are flung upward. Obviously, the bullet that jolted him forward was not the same bullet that hit him at Z190.
These things are obvious to anyone who is not bound by the SBT.
