What is James Chaney Looking Back at?

[Richard Coleman]

In the famous Altgens 6 photo below, motorcycle officer James Chaney appears to be looking over his left shoulder at JFK. Of course, this is impossible, as the Zapruder film shows no motorcycle beside the limo.





However, if you feel strongly that Chaney is ahead of JFK, watch the following:

In this interview, Chaney tells the reporter he passed JFK's limo and went ahead to inform Chief Curry, in the lead car, of JFK's wounds. This is not seen in the Zapruder film either, nor in this still from the Nix film.



Nor do we see a motorcycle, in Altgens' last photo, between JFK's limo and the lead car. When did Chaney pass the limo?

First of all, where does this copy of Altgens 6 come from? It's the best resolution I've ever seen.

Second, although nobody seems to care, notice the 4 black women also looking backwards. What were they seeing I wonder. And my favorite thing in this picture is the guy in the hard hat. I'd pay serious money (if I had any!) to know who he was.
