They had to...they had already concluded that he was the lone assassin In this country a wife cannot be compelled to testify against her spouse.
Marina's civil rights were violated. Someday you may even be compelled to agree.
Good grief. Marina's civil rights were violated when she voluntarily cooperated with the WC? You are going round and round in circles. At first you appeared to dispute that Oswald had practiced with his rifle. Then when confronted with evidence from his own wife that he had practiced with his rifle, you cast doubt on her testimony and falsely suggested that the WC didn't believe it. Now you are arguing that the WC
had to believe it because they concluded that Oswald was the assassin (likely based on the overwhelming evidence of such) and that Marina was compelled to testify (a falsehood). And this wasn't even a trial so it's unclear that any "privilege" would apply. You have invoked multiple falsehoods and inconsistent narratives. Typical CTer nonsense.
