No time for long conversations when your family are being slaughtered. Another non-starter !
By the way,,it was years later, 2002, when Nevilles' call was found,anyway.But it was,and it should have been seen as proof of Jeremys' innocence then,that his father did indeed ring him,,so why do you think it wasn't ?
Nevilles' phone-call was known,,but never shown to the jury,even though it had been entered at the trial. Why ?
