I don't know why. Please enlighten me.
He was certainly one of the best witnesses.
That's him in Z333 to about Z358ish, camera at the ready.
His pictures were on the "wire" soon after.
Altgens stated that he was "about" 15ft away from the President" when JFK was hit in the head with the last shot.
Since the street is about 30feet wide, that puts JFK directly opposite Altgens, who is standing facing the street, camera prefocused to 15 ft, about to snap the shutter.
And thats about Z345 to Z350, which certainly throws a monkey wrench in the whole official shooting sequence.
Remember, also, that in 64, we are ten plus years away from Zfilm release.
The Commitee first tried to ignore Altgens, then reluctantly took his testimony, and filed it away, never knowing that Altgens was a vital "supporting actor" in the Zapruder cinema production.
