Helen Markham was...... The Commission's star witness! Can't get any more positive than that.
Please explain what Markham's confusion during her testimony has to do with her 100% positive identification of Lee Oswald, on 11/22/63, as the man she saw shoot the police officer.
Many conspiracy believers rely on portions of her testimony as if that somehow negates the fact that on the day of the murder, she identified Oswald as the cop-killer.
On the day of the murder, she was taken to a lineup and positively identified Oswald. Nothing in her testimony, given many months later, changes the fact that, on the day of the murder, she picked Oswald.
