LOL can’t resist.
No idea who was behind it, but three pieces of information have always made me go hmmmmm…
1) the motion of the head in the Zapruder film
2) the pristine bullet
And this interview.
Skip to 9:40 and then again to 25:30
I never really looked into this much before.
But I just searched this film and think this doctor is correct.
Pretty good shots either way. Lots of training to hit a moving target like that.
Oswald was placed in juvenile detention at the age of 12 for
truancy, during which time he was assessed by a psychiatrist as "emotionally disturbed", due to a lack of normal family life. After attending 22 schools in his youth, he quit repeatedly, and finally when he was 17, joined the Marines. Oswald was court-martialed twice while in the Marines, and jailed. He was honorably released from active duty in the Marine Corps into the reserve, then promptly flew to Europe
and defected to the Soviet Union in October 1959. He lived in Minsk, Byelorussia, married a Russian woman named Marina, and had a daughter. In June 1962, he returned to the United States with his wife, and eventually settled in Dallas, where their second daughter was also born.
Defection to the Soviet Union
Oswald traveled to the
Soviet Union just before he turned 20 in October 1959. He had taught himself Russian and saved $1,500 of his Marine Corps salary (equivalent to $10,600 in 2020).
[n 3] Oswald spent two days with his mother in
Fort Worth, then embarked by ship on September 20 from New Orleans to
Le Havre, France, and immediately traveled to the United Kingdom. Arriving in
Southampton on October 9, he told officials he had $700 and planned to stay for one week before proceeding to a school in Switzerland. However, on the same day, he flew to
Helsinki. In Helsinki, he checked-in at the Hotel Torni, room 309, then moved to Hotel Klaus Kurki, room 429.
[49] He was issued a Soviet
visa on October 14. Oswald left Helsinki by train on the following day, crossed the Soviet border at
Vainikkala, and arrived in Moscow on October 16.
[50] His visa, valid only for a week, was due to expire on October 21.
[51]
Almost immediately after arriving, Oswald informed his
Intourist guide of his desire to become a Soviet citizen. When asked why by the various Soviet officials he encountered – all of whom, by Oswald's account, found his wish incomprehensible – he said that he was a
communist, and gave what he described in his diary as "vauge [
sic] answers about 'Great Soviet Union'".
[51] On October 21, the day his visa was due to expire, he was told that his
citizenship application had been refused, and that he had to leave the Soviet Union that evening. Distraught, Oswald inflicted a minor but bloody wound to his left wrist in his hotel room bathtub soon before his Intourist guide was due to arrive to escort him from the country, according to his diary because he wished to kill himself in a way that would shock her.
[51] Delaying Oswald's departure because of his self-inflicted injury, the Soviets kept him in a Moscow hospital under psychiatric observation for a week, until October 28, 1959.

Apartment building where Oswald lived in Minsk
According to Oswald, he met with four more Soviet officials that same day, who asked if he wanted to return to the United States. Oswald replied by insisting that he wanted to live in the Soviet Union as a Soviet national. When pressed for identification papers, he provided his Marine Corps discharge papers.
[53]
On October 31, Oswald appeared at the
United States embassy in Moscow and declared a desire to renounce his U.S. citizenship.
[54][55] "I have made up my mind", he said; "I'm through."
[56] He told the U.S. embassy interviewing officer,
Richard Edward Snyder, that "he had been a radar operator in the Marine Corps and that he had voluntarily stated to unnamed Soviet officials that as a Soviet citizen he would make known to them such information concerning the Marine Corps and his specialty as he possessed. He intimated that he might know something of special interest."
[57] Such statements led to Oswald's
hardship/honorable military reserve discharge being changed to
undesirable.
[58] The story of the defection of a former U.S. Marine to the Soviet Union was reported by both the
Associated Press and
United Press International.
[59][60]
Though Oswald had wanted to attend
Moscow State University, he was sent to
Minsk,
Belarus, to work as a
lathe operator at the Gorizont Electronics Factory, which produced radios, televisions, and military and space electronics.
Stanislau Shushkevich, who later became independent Belarus's first head of state, also worked at Gorizont at the time, and was assigned to teach Oswald Russian.
[61] Oswald received a government-subsidized, fully furnished studio apartment in a prestigious building and an additional supplement to his factory pay, which allowed him to have a comfortable standard of living by working-class Soviet standards,
[62] though he was kept under constant
surveillance.
