In researching regarding another issue, I stumbled across this contribution from MTG on Spartacus Educational.
"The lone-gunman shooting scenario now requires that the supposed single assassin completely missed, not just Kennedy, but the entire huge presidential limousine with his first and closest shot. This is the only way to expand the alleged lone gunman's firing tie to over 8 seconds, since there is now wide agreement that a shot was fired before the limousine passed beneath the oak tree. I can't imagine how even a mediocre rifleman could have missed the entire limousine from less than 140 feet away and from 60 feet up. Even the WC labeled the first-shot-miss scenario an "improbability." The limousine would have presented a target that was over 120 square feet in size. Can anyone fathom completely missing a target that size from less than 140 feet away, especially on the first and closest shot?"
Yes, that would have been a ridiculously bad miss if Oswald's intended target was the limousine. Does MTG think Oswald was trying to shoot the limousine? It makes about as much sense to point out that he also completely missed the press bus and he completely missed the overpass. Those were even bigger targets than the limousine.
