Researcher Greg Parker has an interesting theory and that is that Oswald had no knowledge of the upcoming murder. In other words he was completely innocent and the reason why he was murdered was not to shut him up about what he knew about the plot, but just to shut him up. I've thought about this and I agree with this now.
I also believe he WAS being manipulated but unknowingly about the murder itself. I believe he was a [very] low-level agent doing "intelligence" about Communists. Thus, the handing out of the leaflets in NO, getting on TV later about it and looking proudly as he explains who he is, and so on. Doing this allowed him to be photographed where his head could later be put onto the BYP. His alias was also a ruse. Doing this showed him to be a rabid Marxist and so on.
This all started, too, the moment he did the fake defection, then returned. There are others out there who we've never heard from again who also did this kind of thing. Robert Webster was another of them.
He asks a co-worker what the commotion was. When he was told the President is coming, he says "oh." He later says in front of TV cameras that the only reason why he was arrested was because he lived in Russia, then went on to say he was a patsy.
He stated the BYP were fake, with his head pasted. He said he'd be able to show how that could be done [because after all, he worked at a photo place].
He supposedly kills the president but has no grand getaway plan. He supposedly sticks around the building, is dismissed from work, walks over to catch a cab home, gives it up for a lady, takes the bus home, changes his clothes, then takes this long roundabout walk where he supposedly is confronted by Tippit, where he guns him down. Then he goes to the theater. The "6 foot 160 lb" description goes out within 15 minutes of the murder. How do they know this so soon? And it's not even accurate, far from it.

I think that's kinda right, Oswald had no knowledge of the upcoming murder right up until the 19th when the parade route was put on the front page of the Dallas Times Herald, and only then did Oswald start thinking about his plan and even up until the night before, I believe there was still a chance that he could pull out, but after being rejected by Marina and, well, the rest is history.
"Mr. RANKIN. And how did he show that he was upset?
Mrs. OSWALD. He was upset over the fact that I would not answer him. He tried to start a conversation with me several times, but I would not answer. And he said that he didn't want me to be angry at him because this upsets him.
On that day, he suggested that we rent an apartment in Dallas. He said that
he was tired of living alone and perhaps the reason for my being so angry was the fact that we were not living together. That if I want to he would rent an apartment in Dallas tomorrow--that he didn't want me to remain with Ruth any longer, but wanted me to live with him in Dallas.
He repeated this not once but several times, but I refused. And he said that once again I was preferring my friends to him, and that I didn't need him."Thus, the handing out of the leaflets in NO, getting on TV later about it and looking proudly as he explains who he is, and so on.
Imo he was proud because his dream was potentially(to him) becoming a reality, he was starting to be someone, perhaps one day a great famous leader!
Doing this allowed him to be photographed where his head could later be put onto the BYP.
I have attempted many composites and it's not easy finding suitable matching body parts with the right lighting, right film stock, right film grain, etc etc, or just look at the awful examples where famous faces are composited, or look at the obviously fake Ruby and Nixon photo.
This all started, too, the moment he did the fake defection, then returned.
I reckon Oswald sincerely believed that being a communist was a better way of life, read the "Oswald historic diaries" which shows over time his increasing disillusionment.

He stated the BYP were fake, with his head pasted. He said he'd be able to show how that could be done [because after all, he worked at a photo place].
As I stated above, it ain't easy creating a composite photo and besides a backyard photo negative exists and a tell tale indication of fakery is grain irregularity and the film grain is consistent across the entire image.

The "6 foot 160 lb" description goes out within 15 minutes of the murder.
