Oswald is led to believe he is being brought in on a plot to kill the president, and Oswald volunteers to bring his rifle to the Depository...
There you go, that answers about half of your allegations...
Oswald realizes at some point following the assassination, that he might be falsely accused of shooting the gun that he brought to the Depository, so he tries to flee the scene...
Oswald denies all allegations believing an attorney will come to his aid, and that his one phone call - which was diverted from his "handler" and never went through, according to the testimony of switchboard operators - would give him assistance...
Switchboard operators at the Dallas police station claimed that, on the night of November 23, 1963, Oswald tried to make a long-distance call to Raleigh, North Carolina.
According to Ruth Paine’s testimony, Oswald never made a completed call.
Two switchboard operators later stated that they were told not to put the call through and to never speak of it.
No question about it... and most all reasonable skilled attorneys would agree... Hoover and all who tried to "close the case" within 48 hours and pronounce Oswald guilty, acting alone... rushed to judgment, causing great and reasonable suspicion that the accusing parties just might be accomplices in a frame-up...

Ahhh, the old Oswald was as dumb as a box of rocks defence, I like it, because if Oswald even had 1 brain cell he would have known that bringing his rifle to work when the plot was to kill the President would be stupid and highly incriminating.
And then you have Oswald having an epiphany and realizes that his rifle was in the building and likely used to fire the shots that he heard, then says to himself "Gee Whiz, I might be accused of shooting the gun I brought to the Depository, so I better leave, but first I need a coke"?
Are you serious Jake, or are you trying to pull my leg?
