Lets add to your list:
In the cars behind JFK which held Sen Yarborough, Mayor Cabell and his wife, said they smelled gunsmoke, when Oswald was 250 feet behind them and 60 feet in the air with the wind in his face. That means the grassy knoll, 50 feet ahead of them and 11 feet in elevation was the source of the smoke.
There were 14 Dallas sheriffs personnel all said the shots were from the grassy knoll, as well as about 64 witnesses.
Zapruder himself said he thought the shots were behind him which was the knoll vicinity.
Page 71 of David Lifton’s “Best Evidence”, was the analysis of the Zapruder film, frame by frame, when considering the Single Bullet Theory. The FBI lab stated it took 42 frames in which each shot was fired, so when Frame 210 was the shot of JFK in the throat, Oswald’s next shot could have only been in frame 252,yet as the Commission determined: frame by frame Connally is hit in frame 240.4. That was too delayed to be JFK’s single bullet throat shot, and too soon from Oswald’s gun, hence it came from a second shooter.
Don’t forget that Trump has implicated Ted Cruz’s dad
One theory is that the bullet came from a Secret Service agent by accident
