Luke's alibi was the only thing that changed 'dramatically'. It completely fell apart.
Yes we are encouraged to go by this rule, unless of course it applies to Luke's brother Shane, who originally claimed Luke wasn't at home at all at the time of the murder, he was in his room watching porn and masturbating which he wouldn't do if his brother was home. After being "reminded" by his mother, he later said Luke was home and he distinctly remembers because Luke burned their dinner. But it's ok when he forgets, people get confused all the time! But any change in what Jodi's family remember about what was undoubtedly the most traumatic night of their lives, they must be covering up a murder.
Sorry if my replies are getting at all confusing but we seem to be crossing each other's responses a bit.
I haven't been encouraged to go by this rule. Just seems sort of logical to me in less there is a reasonable explanation for the change. Which I would personally be willing to consider.
The problems with Luke's alibi are undoubtedly problems for a lot of people that point to Luke's guilt. I don't know the exact time line of what was said and what was changed and whether a reasonable explanation were given for the changes. This is something I obviously need to read more about, and will try.
But I don't think this one issue excuses the problems with the search party statements. Both issues should surely be considered.
