Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

"The Jack Ruby who killed Oswald was just 5' 8-1/2" tall."

John Armstrong

But, let's hone in on this fact that Ruby was 5'8 1/2". That was just a half inch shorter than Oswald, but it was a lot taller than the Garage Shooter.

That guy is short. He is no 5'8 1/2". We estimate his height to be 5'6". And the same applies to him here:

And here:

The Garage Shooter was 5'6". James Bookhout was 5'6". And Jack Ruby was 5'8 1/2". 

The Garage Shooter was short, I tell you.
