I thought I'd repost this as IMO it explains why there were anomalies - and why there is nothing sinister about them.
This link is very informative on the subject.

In a crime situation memory is influenced by many factors such as stress, the presence of a weapon and even just the desire to help police solve the crime.
"Police know how fallible the memory can be," says Steve Retford, a former head of the investigative skills unit at GMP and now specialist interviewing adviser with the force.
"They also know this is usually not through mischievousness on the part of the witnesses, but through stress and shock."
Take the case of Jean Charles de Menezes, shot at Stockwell Tube station in 2005 by police who mistook him for a suicide bomber.
Eyewitnesses said he had vaulted a ticket barrier when running away from the police. In
fact it was later shown by CCTV that Mr Menezes had walked through the barriers, having picked up a free newspaper, and only ran when he saw his train arriving.

You might ask how on earth someone could get that so very wrong - and yet more than one person did.This is why I think it's wrong to claim that because there are inconsistencies in description/times etc given in statements by 10 different people (especially at such a stressful time) - it is proof that lies were being told -when quite clearly they are all displaying perfectly normal human behaviour -
when it comes to memory recall.
