The frame up would require the following:
1) Frazier's sister has to move near Ruth Paine. Frazier has to move in and obtain a job at the TSBD. So two families.
2) Paine has to get Marina to live with her. So Oswald's wife.
3) Marina has to agree to move in with Paine.
4) Paine has to become aware of the job opening at the TSBD.
5) Oswald has to agree to apply and take the job. Add Truly.
6) Truly has to agree to hire Oswald and retain him until the assassination.
7) Oswald has to agree to remain on (his job history is not the most dependable) and show up on the day of the assassination. Add Oswald.
JFK has to come to Dallas during the appropriate time frame. Add JFK and members of his government.
9) Oswald has to order or an elaborate hoax has to be arranged to forge documents, pictures and force witnesses including his own wife and employees of Klein's to confirm that he ordered and received a specific rifle with a unique serial number. Add Klein's and witnesses that confirm Oswald possessed a rifle.
10) the motorcade has to pass the TSBD. That brings in the SS into the plot since they make that decision.
11) Oswald has to be somehow convinced to make an unplanned trip to the location where his rifle is stored the night before the assassination. He has to carry a large package the next morning or Frazier and his sister must lie about this.
12) A multitude of evidence has to be planted at the TSBD unnoticed by anyone including the gun, bullet casings, bag. Oswald's prints have to be found on many incriminating items. So the DPD and FBI are involved. Somehow the conspirators have to ensure Oswald is not in a location where someone can give him an alibi at the moment of the assassination. No easy task. Add more people.
13) There are allegations that someone is turning the power off in the building for some unspecified purpose (didn't happen but some CTers claim it did). So add another person.
14) You would need someone to actually assassinate JFK if it wasn't Oswald. So add at least one assassin who somehow gets away completely unnoticed. So likely had assistance. Add more people.
15) Somehow the conspirators have to ensure that no one has a picture or film of the real assassin. Add a team in DP.
16) Any evidence such as bullets or bullet fragments that don't come from Oswald's rifle have to be recovered and replaced. Add a team that has access to the body, any wounded person or other such evidence for the medical procedures etc. Somehow coerce the medical folks to lie. Add dozens more.
17) Add a team to kill Oswald after the assassination that involves recruiting a person willing to go to jail for the rest of their lives. Coordinate the murder of Oswald including getting access to do it. Hope that he doesn't screw it up or talk after the fact. Add dozens more to arrange Ruby's act and control what he says in custody for however long he lives.
18) Ensure everyone at the DPD, FBI or involved in any subsequent official investigation is on board with the plan. Add folks to cover up for decades to the present day if paranoid CTers are to be believed including somehow controlling the media.
Grand total. A cast of thousands from various walks of life including random citizens, family members, state and federal law enforcement, doctors, politicians, a team with a multitude of assignments before, during and after the assassination etc. The alternative is that Oswald put his gun in a bag, found a shooting location, and pulled the trigger. As the evidence confirms.
