What has this got to do with Amarals's lie about JT identifying Murat?
How many times has it got to be pointed out that different people have different perceptions of time and distance and different levels of the power of recall. The differences you quote above- for example 5 minutes - would be regarded as perfectly normal by the police. They don't expect perfect accuracy. Neither do they expect different people describing the same incident - all to give the same account.
Quote from DC Ferguson (JT's rogatory statement)
4078 “You know, we can take a statement from people, if an incident happened outside and there was a group of people watching it, everybody would have a different take on what they had seen”.
Unquote.
Why do you find that so difficult to understand?
They write papers about it ...
Recent research on memory, especially in the context of witness statements and interview techniques is highly relevant.
This article examines also the evidence for any effects on memory caused by weight loss/malnutrition, minor traumatic brain injury, raised stress hormone levels, post traumatic stress disorder, sleep deprivation, depression, and pain.
In the light of these studies it is contended that the assumption that discrepancies and omissions undermine credibility cannot be justified; there are alternative explanations for these differences which are at least equally likely and should be ruled out before testimony is disbelieved.
