So far as the tight 7.5 minute window is concerned I've concluded it's analagous to watching a magician. You don't necessarily need to have to understand how he did it to know he did and that it wasn't by magic.
Rereading the evidence on the screaming it seems that given by SA and the Claremont witnesses is wildly different. SA said it lasted 4-7 minutes, the female Claremont resident said...
“I told Drew to be quiet so I could listen further and I heard it around three times. It lasted five to ten seconds each scream and there was a period of 15 to 20 second between the screams that I heard.
That's just 70 seconds, max!
So discounting they heard separate incidents it shows how unreliable recollections can be, and I suggest how one may only attach limited weight to them.
