Hey, Jack. To me anyway Oswald was involved up to his neck ... Yes, most likely ... not the shooter.
Here's my take on his involvement.
If you look at what the LN's support they have two big things going for them.
One - the physical evidence
Evidence like the MC rifle which Oswald smuggled into the TSBD, disassembled (including a useless scope) and placed in a paper bag, which he reassembled on the 6th floor without leaving a single finger print on the rifle, scope, clip and ammo? How was it even possible to NOT leave his prints on the rifle? And why weren't his prints all over the barricade of boxes near the SN?
Evidence like the 3 spent hulls in a tight group near the window in the SN which Fritz picked up with his bare hands, then later staged for photos in a more "believable" arrangement?
You mean like the 6+ BYPs with Oswald holding the murder weapons and commie lit, that Marina said she only took 2 of and burned one? And how several photos showed up in the darndest places including a darkroom cutout of a BY photo that had not even been submitted into evidence. Baaa.
Never mind that no one has matched Oswald's shooting using a MC and a wonky scope, 3 shots, 2 hits in under 10 secs. And why would Oswald include the scope with the disassembled MC when he knew he would be using the iron sights? Ans: because the MC had to include the scope to match the rifle he was holding in the BYPs, as part of his sheep-dipping.
And how did 1 of those FMJ bullets somehow explode in JFK's head? And how did the MB crash thru flesh and bone and magically show up on the wrong gurney, without a trace of blood, flesh or bone on it, in magical swimming pool condition? Note, all questions are rhetorical.
and .... and ... and ... his own actions
Now let's just look at the latter for a second.
Just before the Big Event as you put it.
Goes home Thursday ... not his regular routine.
Leaves wedding ring and a sizable amount of money behind Why?
Well, to me, he is saying Good-bye and I don't know, given the events of the day,
how anyone could think otherwise.
Brings a package to work.
Tells Frazier he won't be needing a ride home.
Walks well ahead of Frazier going into the TSBD.
Gees, talk about telegraphing what he's about to do.
Now, let's just say Oswald was part of a team of two to three people.
And let's say further that they were going to escape in a station wagon
and he's job was to direct the police's attention to him. To be a decoy of sorts.
Him having his own escape plans AND them having their own plan by leaving by plane
at Red Bird Airfield.
So ... if this was Oswald's plan where would he be, but on the lower floors?
Staying in the background. Not drawing attention to himself.
Since he was involved he'd have no WTF moment with anyone. No asking of questions.
Nothing. Maybe drinking a pop. Just biding his time so he could calmly walk out of the building
which was sure to be sealed off in let's say, 5 -10 minutes, or so he thought
And .. it goes on but this is what I believe took place and I still maintain that ALL assassins
were captured that day and then ... given the identity of these assassins all roads had to lead to Oswald
acting alone.
Just my opinion of course with scanty evidence to support me.
I agree that all of Oswald's actions indicate his degree of involvement but the bottom line is if Oswald was not the shooter then he was part of a conspiracy. And if this was a conspiracy then Oswald was not a lone nut. He could have known that he was the designated patsy from the get go, which is why he went along with all the sheep-dipping. But to go along with it all, he must have been promised a safe escape and refuge out of the country. I'm sure he knew the risks going in but he naively thought the CIA had his back. Instead he was silenced right in front of the Keystone DPD, who yet again achieved plausible deniability thru the guise of ineptitude. Oswald was exactly what he claimed to be, a patsy that knew too much.
