The WC testimony of Mary Bledsoe
The only witness who was shown the actual evidence she was required to testify about (the shirt Oswald was wearing when he was arrested) at her home just prior to her deposition. That Mary Bledsoe?
Mary Bledsoe positively identified the shirt well before her deposition. Well before she was ever asked to give a deposition actually. She was shown the shirt on Dec 4, 1963 by two FBI agents and was able to positively identify it for them. She did not receive notification that she was required to appear before the Commission until March 1964.
