In the link you provide Tague is hit well before z207. Zapruder shows no meaningful reaction from agents Hickey, Landis or Ready up to that point, who all testify they reacted immediately to the first shot, turning to look "rear right". Zapruder refutes this model. The first shot must come after z207.
At the moment I have it something like this:
1st shot - z223 - passes through JFK and Connally
2nd shot - z313 - headshot
3rd shot - ? - hits piece of concrete south side of Elm, fragment goes on to hit Tague
The West survey, as revealed by the late Tom Purvis, shows that SS, FBI etc. ..knew the location of hits.
Z207
Z312
Z350
Connally seems quite mobile at Z275, and upright. Not the actions of a man who had a massive back, chest wound.
Might want to consider the political future of a man who did nothing to protect JFK.
Also, his WC testimony ends with an apology of sorts. For not doing anything. Very telling.
Well worth reading.
