It sure seems as a matter of extraordinary accomplishment that Lee Oswald [if he wasn't a native student] wrote in the Cyrillic far better than he did in his/our own native Latin alphabet. How do you suppose that was?
For example here is a link to the Warren Report pages of his notebook/address book.....
https://www.aarclibrary.org/publib/jfk/wc/wcvols/wh16/pdf/WH16_CE_18.pdf Below is page one and two of the heralded "Walker note" that Lee allegedly wrote Marina before allegedly vanishing to pop a cap into a general [for no reason at all] Take a good look at this penmanship. No sloppyness, markovers, or scratchouts, at all! [well not on page one anyway. Did Oswald write it? If so--he appeared quite accomplished. If he didn't---- it appears quite fishy.
1. This is the key to the mailbox which is located in the main
post office in the city on Ervay Street. This is the same street
where the drugstore, in which you always waited is located. You
will find the mailbox in the post office which is located 4
blocks from the drugstore on that street. I paid for the box
last month so don?t worry about it.
2. Send the information as to what has happened to me to the
Embassy and include newspaper clippings (should there be anything
about me in the newspapers). I believe that the Embassy will
come quickly to your assistance on learning everything.
3. I paid the house rent on the 2d so don?t worry about it.
4. Recently I also paid for water and gas.
5. The money from work will possibly be coming. The money will
be sent to our post office box. Go to the bank and cash the
check.
6. You can either throw out or give my clothing, etc. away. Do
not keep these. However, I prefer that you hold on to my
personal papers (military, civil, etc.).
7. Certain of my documents are in the small blue valise.
8. The address book can be found on my table in the study should
need same.
9. We have friends here. The Red Cross also will help you [Red
Cross in English].
10. I left you as much money as I could, $60 on the second of
the month. You and the baby [apparently] can live for another 2
months using $10 per week.
11. If I am alive and taken prisoner, the city jail is located
at the end of the bridge through which we always passed on going
to the city (right in the beginning of the city after crossing
the bridge).
