You forgot the witness who got the best look at Tippit's killer and whose description of the murderer doesn't
match a photo taken of LHO while in DPD custody on 11/22/63.
Testimony Of Domingo Benavides
Mr. BELIN - Where were you when your vehicle stopped?
Mr. BENAVIDES - About 15 foot, just directly across the street and maybe a car length away from the police car.
~snip~
Mr. Belin: Let me ask you now, I would like you to relate again the action of the man with the gun as you saw him now.
Mr. Benavides: As I saw him, I really--I mean really got a good view of the man after the bullets were fired he had just turned. He was just turning away........
~snip~
Mr. BENAVIDES - I remember the back of his head seemed like his hairline was sort of--looked like his hairline sort of went square instead of tapered off. and he looked like he needed a haircut for about 2 weeks, but his hair didn't taper off, it kind of went down and squared off and made his head look fiat in back.

You forgot the witness who got the best look at Tippit's killer...
No. It could easily be argued that each of the Davis girls and Scoggins got better looks at the killer than did Benavides.
Barbara Davis: Picked Oswald out of a lineup.
Virginia Davis: Picked Oswald out of a lineup.
William Scoggins: Picked Oswald out of a lineup.
Domingo Benavides: Decided that he did not get a good enough look at the killer to attend a lineup.
Duh.
