The official story has long held that police officer Marrion L. Baker found Oswald in the second story lunchroom of the Texas Schoolbook Depository (TSBD) within 90 seconds of the shooting. Officer Baker had to have run immediately and straight for the TSBD in order for this to have occurred so quickly. And indeed the Darnell film does seem to show Baker doing just that.
But it's a mere illusion, as I will show here in this post. Baker didn't run straight for the TSBD. Not to its entrance.
