Nope! He takes a quick look down the extension, and then resumes looking ahead-----without changing his path
That's it, Mr. O'Meara? That's really all you've got? 'Baker was such a moron he didn't pay attention to where the front entrance was'

The Darnell clip shows he was looking up the Elm Street extension while he was running towards the steps.
What else do I need?
He describes what he saw happening down in the direction of the Grassy Knoll, he was focused on that while he was trying to make it to the steps.
It's as simple as that.
Have a think about the tale you have woven in place of this simple explanation.
Baker
is looking up the Elm Street extension as he runs towards the steps in the Darnell clip.
You cannot get away from that.
In his WC testimony he stresses he is focused on the area by the Grassy Knoll at the time in question.
You can't get away from that.
Compare the simplicity of this to what you have to offer.
