From Bowles’ introduction of chapter six (which I posted earlier in this thread):
While their recollections are presented in the first person, their comments should not be taken as unalterable quotes. Too many years have passed for them to remember with unimpeachable certainty what they might have said earlier and what they say now. Accordingly, what they say here should be considered for the meaning rather than exactness.
And from Westbrook’s WC testimony:
You know, I didn’t review my report before I came over here - I didn’t have a chance. I just came off of vacation and they hit me with this this morning as soon as I got to the office.
Even in the best of circumstances there are normally inconsistencies between the accounts of various people. If everyone’s accounts agreed totally and all the Ts were crossed and the Is were dotted, it would look suspicious to me.
