Oswald confessed to his own wife.
Her testimony matters, but it doesn't
prove anything. Not sure why this is such a difficult thing for some to grasp.
In any other case, that alone wouldn't be enough evidence for an arrest if there's no proof that the suspect was at or near the crime scene at the time when the crime was committed. She wasn't an eyewitness to the crime. For all we know, the suspect could've lied to the witness (assuming the witness told the truth).
It matters for something but legally, it's not proof.
She was trying to protect herself from any claim that she should have known that Oswald was a dangerous person capable of a political assassination prior to Nov. 22. Her every incentive was not to acknowledge this fact but the evidence left her no choice. [/b]Walker home found
You could be right but we don't know if your speculation is correct. Only Marina knows. Don't confuse your speculation with proven information.
Because of her inconsistent statements, poor memory, and the fact that she was an immigrant who feared prison or deportation, it's reasonable to be skeptical of her statements that incriminated her deceased husband.
The note that Lee left behind didn't have a date, didn't mention Walker, and wasn't discovered by the police when they searched Ruth Paine's home. It was found after Oswald was killed. Handwriting can be forged. There's tons of reasonable doubt surrounding the note.
I don't think it would be admitted as evidence if Oswald hypothetically were tried in court for the Walker shooting. Marina wouldn't be allowed to be a witness either.
So you know I'm right when I say he probably wouldn't have been convicted of the crime based on the available evidence.
