Staffan and Pete, having read your analysis, Looking at the Tippit Case from Another Angle, it seems a concise outline using the known facts.
Roger Craig sees Oswald getting into a Rambler. (A sudden thought: Was it David Morales at the wheel?) The trip is from the Depository after the Baker-Truly encounter, to the Texas Theater to meet a contact. Lee pays for a ticket.
An impersonator goes to the rooming house to pantomime the taking of a jacket and gun. I agree with you, and with Armstrong that Lee did not have a revolver. A jacket is dropped. Marina wasn't read in: she didn't recognize the jacket; its laundry mark was counter to her washing Lee's clothes.
Tippit is sent to a killing zone and killed by two men, neither Lee. Witnesses are threatened or coached.
At the theater an impersonator enters without paying and Brewer gets Postal to call police. The appearance of two dozen reminds us of the mass of police quickly on-scene at the assassination of Malcolm X/Malik Al-Shabazz in '65; the fifty FBI agents combing the wreckage of Dorothy Hunt's plane at Midway in '72.
Any revolver at the theater was brought by police.
So, what next? Walker. Post mortem. Though Lee was not a suspect for seven months and Walker said the police changed the bullet from a 30-30 to a 6.5.
Let's make him a Commie defector, a Castro cheerleader, a wifebeater, a psycho from New York childhood, blame him for downing Powers' U-2.
Then kill him in a staged media event on live television.
I saw it live.
Honk. Here he comes. Honk. BANG. Down goes the eevil Commie copkiller.
The connections to Collins are lovely. And the ride out to Roswell--was it Morales with him?
The scene on the Plaza was under control. Witnesses were processed in the manner used in '68 in the RFK assassination. The photos and films were confiscated and damaged, destroyed, "lost".
The witnesses interrogated, intimidated--if necessary, eliminated.
We would agree the truth is before us: the assassination of John F Kennedy allowed the business model to continue unobstructed.
It continued the process of re-education of the people that they are powerless before unseen sponsors using plausibly deniable facilitators and mechanics.
Your outline of the tactical is useful: it accounts for the events we know happened and for some we may have been made to believe happened.
In the large view, the post-assassination handling of Oswald was planned and executed to isolate, control and eliminate him while painting him as the eevil lone assassin.
Weisberg in McKnight revealing the Oak Ridge confirmation of DPD's negative cheek paraffin test for Oswald, but positive for seven actual MC shooters shows he did not fire a long gun.
Deconstruction of the paper trail for his alleged Tippit murder weapon and accounts such as Clemons' show he did not shoot Tippit.
The Walker allegation is without support.
Could Kafka have written a better plot?
There is even a large cockroach.
