Where to start on this, what BigHunter states about what this Morley character believes is something very akin to what I am believing as of today. Starting mid last week I started doing whatever amateurish research that I could on in the internet and found myself going down all kinds of rabbit holes. Nothing to do with the shooting or trigger pulling, but more about who Oswald was and his activities leading up to 11/22/63, with an emphasis on his time in CDMX and to a lesser degree his time in the USSR and how/why he got there and such.
I am no experienced expert on any of this, but I am entitled to have my own opinions and after "wasting" prolly 10-12 hours, possibly a little more, on this stuff a few things stand out to me. Relaying all of the "how's and why's" of my opinion would take much more time to write, summarize and organize correctly, and footnote. Bluntly, I am just not willing to spend that kind of time.
I have no opinion about the actual shooting, and can believe that LHO did it alone but there exists the possibility of the involvement of others. I also believe that LHO might have been wound up in a skewed manner by the CIA, who I believe wanted nothing to do with him after his time in Russia but to me it is obvious that LHO had some kind of covert support/training/prodding/assistance or whatever it might be prior to him defecting. I think it is likely that LHO was recruited, and recruited might not be the right word as "picked out" might be better, by a front or offshoot of the CIA. For what particular reason? I have no idea, but there is always a place for an easily deniable and easily disposable "useful idiot" in the nebulous world of the 1950's & 60's CIA, and possibly FBI. And after a mostly vapor locked life this approach by whatever group or entity LHO might have thought himself desirable and I believe somewhere along the way, likely prior to his "defecting to Russia" whoever had approached and was crafting LHO cut bait with him due to him being somewhat of an un-malleable dolt.
I believe LHO had delusions of grandeur of some kind and someone from the CIA spotted him and found out about his background, likely in Japan via all his trouble there, and figured that LHO could be used as a throw away for something, and likely it was never meant to be assassinating the president of the US. The more I read on LHO, and the supposed actions he took, prior to the JFK killing the more I think that it is highly unlikely that a bumbler like him could have done all that he has supposed to have done without some kind of training or help or guidance. Think about this, how many 22 year olds in the United States in 1962 would have been able to get a passport, figure out that an easy way to get to the USSR would be via Helsinki and then spend over two years in the USSR? And then figure out a way to get hitched, get back to the US and just kinda meld into society again. There are a ton of "should been or should happened" with LHO.
One major "should have happened" is that most any American that traveled privately to the USSR, much less one that tried to renounce his US Citizenship and state to the State Department that he was about to obtain Russian citizenship, would have had a "Lookout" card placed in their file in the State Department Passport division. Somehow LHO didn't have that happen after he received a Single Use Return to the US passport from the Moscow embassy. Thus, he was able to obtain the second passport without any issue. Why? Those interviewed about this just chalk it up to "must have been an oversight". LHO caused the US Embassy a case of heartburn and redass, he could not even afford his passage back to the US. LHO, being the savvy world traveler that he was, wrote to his mother to send money and she sent a check(s) which were useless in the USSR. He could get to Moscow, renounce his citizenship, yet he asked his mom for checks? Makes no sense.
In the files that I read, supposed correspondence from LHO to the Moscow Embassy is listed. I believe those "letters" were either fake or doctored because by all accounts LHO would likely have not written in the style and vernacular that he did. He was a very capable communicator and writer for a high school drop out. After being basically broke in Minsk for a long spell, he gathers up some funds and has to borrow the rest from Uncle Sugar, which he repaid ahead of time once back in the US (pretty impressive for a guy that supposedly despises the US), and he returns to the U.S. Then he gets wanderlust again and gets a passport, no "lookout" card in his file, and lists the countries he is going to visit as several in Europe including the USSR and The Dominican Republic (WTF?).
Then he goes to Mexico, again making an arduous bus trip (it is arduous today) from NOLA to CDMX with a stop in Monterrey. And there things really get nebulous. There are so many varying accounts and suppositions that there is no telling what went on there. But damn skippy, almost within hours of it being known that LHO killed the president the Mexican DFS runs a dragnet and pings on several folks that have had supposed contact with him and picks up many of them. Again, this will get really long if I try to summarize the hours of reading that I did, but suffice to say that the DFS, (sorry, the Mexican intelligence) service deeply penetrated by the CIA ,who had 3 future presidents of Mexico on the payroll, 2 of whom ran the government and the DFS reported to.
What I believe is that it would be very non-kosher, even today, if the depth of CIA involvement and manipulation in Mexico ever were truly exposed. I can't help but think that the reason Mexico was a haven for so many leftist subversives is that the CIA was encouraging this at best, so that they could use the DFS to surveil and penetrate these movements/people, and possibly at worst is that the CIA was actually sponsoring these leftist movements and could easily do so via Mexico. Talk about redundant job security.
All in all, I think that there is much more to LHO than we will ever know and the CIA has had 60 years to scrub things. I also believe all the convoluted disinformation, wild goose chases, outlandish rumors with a shred of fact, and rabbit holes were created on purpose to muddy the waters around what the CIA either did or didn't do.
