You have not explained away the need for the TSBD to be "secured" by the conspirators before and during the assassination.
You have not explained away the need for Oswald to be restrained (by the conspirators) before and during the assassination.
Oswald cannot be permitted to be free to come and go lest he walk outside to look at the motorcade or someone comes inside just before the shots were fired and sees him. Lee Oswald (the patsy) cannot be permitted to have an iron-clad alibi.
You have not explained away the need for the TSBD to be "secured" by the conspirators before and during the assassination.That need only exists in your imagination. We are talking about one man slipping into a near empty building because nearly everybody was outside watching the President. If the assassin ran into anybody he could easily abort.
You have not explained away the need for Oswald to be restrained (by the conspirators) before and during the assassination."I'll meet you at the luchroom on the second floor at 12.30"... That would be all it would take...
Oswald cannot be permitted to be free to come and go lest he walk outside to look at the motorcade or someone comes inside just before the shots were fired and sees him. Lee Oswald (the patsy) cannot be permitted to have an iron-clad alibi.When the conspirators also control the cover up, there would be no problem. Witnesses that say they saw him could be persuaded that they were mistaken or they could simply be ignored, as was done with Carolyn Arnold, Dorothy Garner and others.
