So what do you make of Helen Markham's statement to Eddie Barker of KRLD TV Dallas?
A year long media indoctrination, telling the people that Oswald was indeed the killer, and a subsequent offical report, saying basically the same thing, would convince most witnesses that any doubts about the identity of Tippit's killer they may have had was probably mistaken.
Rationalisation has a tendency to influence people's thought processes. Back in those days even Marina Oswald believed her husband killed Kennedy and Tippit, so why shouldn't Markham? She basically had two options; (1) stick with the official story and be done with it or (2) or say something that disagrees with the narrative and get into all sorts of trouble with people who disagree.....
The Barker interview has no probative value.
