How could any FBI agent with two brain cells to rub together investigating Oswald as a Russian Asset , not be aware of his criminal record showing propensity for Violence towards authority figures and illegal firearms given his record convictions for both?
"April 11, 1958 Court-Martial: Partly Printed Document. Two two-sided pages, 8" x 12.5", Atsugi Japan, April 11, 1958. Being the "Charge Sheet" which contains Oswald's typed information as the accused, as well as names of witnesses, information provided by commanding officers, Oswald's punishment, and other remarks. On October 27, 1957, Oswald accidentally shot himself in the left elbow with his personal .22 derringer. Possession of such a firearm was in direct violation of "a lawful general order... by having in his possession a privately-owned weapon that was not registered." Following a three-week stay at the Yokosuka Naval Hospital and various unrelated delays, Oswald's court-martial commenced on April 11, 1958, at which time Commanding Officer and Convening Authority Lt. Col. N.D. Glenn made his judgment. Oswald was demoted from private first class to private and ordered "To be confined at hard labor for 20 days, to forfeit $25.00 per month for two months and to be reduced to the grade of private... Approved and ordered executed, but the confinement at hard labor for twenty days is suspended for six months, at which time, unless the suspension is sooner vacated, the sentence to confinement at hard labor for twenty days will be remitted without further action."
June 24, 1958 Court-Martial: Partly Printed Document Signed. Two two-sided pages, 8" x 12.5", Atsugi Japan, June 24, 1958. This "Charge Sheet" contains Oswald's typed information as the accused, the names of witnesses, information provided by commanding officers, Oswald's punishment, and other remarks. Just two months after his first court-martial, Oswald was brought before a second military court on charges that he insulted and assaulted a superior officer."
On this thread as well, I must put your "violent criminal" portrayal of Oswald in perspective:
1. An 18-year-old kid manages to shoot himself in the elbow at his locker in the barracks with a .22 Derringer that he possesses in contravention of military regulations. The discharge occurs while he is reaching into his locker for shaving cream. He is charged with "wrongful conduct" but not charged with the more serious "misconduct' because it's a minor incident.
2. The same kid, while drunk, accidentally (that was the court finding) spills a drink on a Technical Sergeant, who then shoves him, and the two end up in a minor altercation outside. He is convicted of only one of the charges against him - "using provocative words."
3. For 3+ years in the USSR and U.S., the individual's only brush with the law is for disturbing the peace in violation of a New Orleans municipal ordinance, for which he is fined $10.
4. He was not "under investigation for being a Russian asset." As a former defector with a Russian wife who openly engaged in pro-Castro activities, he was of routine interest to the FBI with no indication he was dangerous or a Russian asset.
5. At the time of the JFKA, he was working as a temporary order filler in a grungy warehouse with some 95 other people, most of whom were employees of well-known publishing companies. He did not have a "workplace on the 6th floor" - it was simply one of the floors from which he filled book orders. There was no "sniper's test" until the day of the JFKA. Every window in every building along the motorcade route was a potential sniper's nest (not to mention all the other locations from which CTers think shots were fired!).
You are simply engaging in the sort of long-after-the-fact, ad hoc "analysis" that is the lifeblood of conspiracy thinking. The day before the assassination, Oswald was simply a young oddball the SS probably should have been told about. After the JFKA, he was an obvious threat, a ticking time bomb, a violent criminal who should have been in shackles a week before the assassination. The reality is, if the SS had been told about him, they like the FBI might well have concluded he was not a threat.
