And how does any of that show Oswald isn't guilty? Do you have a different version of the Zapruder film? And even if reports of a second person on the 6th floor was verified, how does that prove that the second person was involved or that Oswald wasn't?
I'm pressed for time so I must be brief. The same ol' Z film shows evidence of more than one shooter and evidence of a frontal shot.
Reports of others on the second floor don't confirm: 1. Oswald's description, 2. that only one person was there at the alleged scene of the crime or, 3. time placement there.
And how does that show an error in law? The only point of that statement is to try and imply that Oslwald's murder is proof of a conspiracy because Ruby was in on a conspiracy.
YOU said that you can only exonerate Oswald, as one example, if there was an error in law, but there is NO error in law regarding Oswald, because NO law was applied to him, since Oswald was killed before a trial could be held. Remember, Oswald was not convicted.
The issue with Ruby is separate. Ruby was later discovered to have significant underworld connections (Carlos Marcello controlled Texas through others). To believe that he silenced Oswald to spare Jackie Kennedy the grief from a trial is ridiculous (ample photographic evidence that Ruby was stalking Oswald at the police station days before he killed him). There are other reports of Ruby being seen with Oswald at his strip joint or near the Tippit killing.
Ruby's statements to the press are interesting here:
And once again trying to prove a conspiracy by saying the authorities were in on a conspiracy.
I merely proved to you that there indeed was a cover-up (Chief Counsel Blakey, Senator Schweiker, etc.). I didn't say that the "authorities" were in on a conspiracy. However, that doesn't mean that they didn't think there was one, and concealed that fact from the public. (Did you not read the text of LBJ's interview years later that I posted, wherein he didn't think Oswald acted alone?) Some people were merely following orders. Don't forget the classified files. (Where's there's smoke, there's fire)
[Edit]: The cover-up and the murder conspiracy are independent acts. There could be some overlap but on a small scale. Then there could be accessories after-the-fact who knew about stuff but didn't do anything about it.
You still didn't answer my question why the records were sealed for years if Oswald was just a lone nut communist? (Originally, the records were sealed for 75 years, then 25 years from 1992 or after the movie JFK - they should be released October 2017).
