H.B. McLAIN: Not in position to record impulses ala BBN
By the time the Altgens photo below is taken , at least two shots
have been fired according to BBN account of the time of the shootings.
If H.B. McLain had the stuck microphone to record the impulses
of those two shots and the subsequent ones, he should have
already been at the corner of Houston and Elm BEFORE the
Altgens photo was taken.
In the Hughes frame
above
on the right we can see
Dallas motorcycle policeman H.B. McLain rounding
the corner from Main onto Houston street.
The blue arrow points to the vice presidential secret service car.
In the Altgens picture
at the top of the page we can see the same
vice presidential secret service car still in the intersection of
Houston and Elm.
Keep clicking on the following series of pictures to see McLain's positon in the motorcade.
He arrived at Houston and Elm with the two Mercury Comets designated as Congress
cars 1+2 in Todd Vaughan's SCHEMATIC LISTING OF THE MOTORCADE.
