Lee Harvey Oswald lives to be put on trial?

There is a movie made in 1977 called the The Trial of Lee Harvey Oswald but it does not give much a answer wheter Lee is guilty ore not as he like in OTL gets shot death before his verdict is announced.

His lawyers would have probably been able to cause so much doubt into who actually pulled the trigger that the trial end result would have been a mistrial or not guilty verdict.
The angles of a Mob hit were deep and multiple.

Yeah, I don't believe these conspiracy theories. Besides, even if they were true, and there were other shooters, Oswald wouldn't have been off the hook, because he would still have been a shooter: he would just have been one of several, instead of the only one.

(As a fun fact: when JFK's assassination took place, there was no federal law making it illegal to kill the President of the United States. Therefore, the assassination was not treated as a federal crime; instead, it fell under local jurisdiction. This makes me wonder: what if the assassination had taken place on some unincorporated, unorganized territory with no local government to speak of? Oswald could have shot JFK in the face on some beach on some outlying atoll, and there could have been *no* doubt that it was him - but, it wouldn't have been possible to do anything because he wouldn't have been breaking the law...)

All the evidence shows Oswald did it on his own. If Oswald had lived to stand trail, it would be harder for the conspiracy theorists to spread their lies. There would be so much coverage of the trail that more people would know the facts. Oswald will be found guilty of murdering President Kennedy and Officer Tippit. He will get the death penalty. He will not be executed. His appeals will last until late 1967. There were no executions in the US from July 2, 1967 until January 19, 1977. During those years opponents of the death penalty stopped the executions with law suits. A successful appeal would add years of delay. Jack Ruby's death sentence was overturned. Texas law forbid using at trail statements a defendant made before they talked to a lawyer. Unless it was put in writing and signed before witnesses. The prosecutors violated that law by using the statements Ruby made to police after his arrest. The prosecutors would be tempted to use the lies Oswald told during interrogation. As well as his admission that he picked up the pistol he used to kill Tippit when he went back to his room after he left work. If prison security was good enough so that Oswald could live unitl 1972, then he would have been spared execution. That year the Supreme Court threw out everyone's death sentence. 

Yeah, if he did it in Germany, he could certainly have been prosecuted under the German legal system. I'm thinking more of places like the United States Minor Outlying Islands. (Or, perhaps, on any federal land? I don't know whether it would be possible to apply any local/state laws there - but if only federal law applies there, then Oswald wouldn't have committed a crime had he assassinated JFK in a national park or something )
