There is nothing damaging in those police interviews. Hence the prosecution never used anything from them against him.
The best you can do is distort the contents and hope nobody actually reads them.
Over 30 'No comments' & 'can't remembers'. Over 10 -don't knows' & 'can't say'.
Several one word answers as well as vague answers such as 'not really', 'I think so' & 'less than 40 but more than 10 !'
The police had to often ask the same simple questions several times in order to get a straight answer.
He initially said he phoned Julie before the police & could not remember what they spoke about at 3am. He eventually said Julie was phoned after the police phone call.
He suggested the dog fired the second shot at Sheila
He also suggested Nevill said 'She', not 'Sheila' !
He didn't dispute that Sheila could not have shot herself twice.
