Note that we still have three images of Bookhout from the time of the assassination, two from 11/24 and one from 11/23.
Those are from 11/24, and this one is from 11/23, talking to Oswald in the hallway:
Now, I wish we had more, but I'm glad we have these three. And in connection with the one from 11/23, we also have images of him from behind which we can compare to the Garage Shooter:
And they compare very well. So, the case against James Bookhout, is, in the parlance of Captain Will Fritz, "cinched". James Bookhout, and not Jack Ruby, was the Garage Shooter of Lee Harvey Oswald.
