No two men remember combat exactly the same way so Kerry has been extremely lucky that 9 out of his 10 crewmen have almost identical stories about his valor during various firefights and skirmishes. But memories can vary from person to person; Gardner insists that the Kerry he knew in Vietnam was a singularly un-heroic figure. He dismisses the glowing eyewitness accounts of his crewmates Jim Wasser (Radarman), Bill Zaladonis (Petty Officer), Drew Whitlow (Boatswains Mate) and Stephen Hatch (Boatswains Mate) as bunk. Kerry sat some of them down and convinced them to buy into his side of what happened over there, he explains in bizarrely conspiratorial fashion with no evidence to back him up. When youre as persuasive as Kerry its not hard to make a guy change something that he saw.
If this did happen, it could be a good example of implanting false memories. The crewmen were a tight bunch of people, more than willing to back each other up. They were also in the limelight because a national figure like Hanoi John was paying attention to them. It wouldnt be difficult for Hanoi John to use this to his advantage.
