Joe Karams version of what constable Andrews said at court, from radio live.

Karam [Quote] David Bain did faint, when he fainted he crashed down between, and banged his head, the officer Andrews who was with David when David fainted and crashed down behind the bed saw David crash down behind the bed and it was the constable Andrews who gave this evidence about him crashing down and banging his head on the wall by the window sill in his bedroom on the right side of his face, now that’s the evidence in the trial.

And here we have what the officer Andrews actually said in court in 2009, from page 336 of the transcripts.

Constable Andrews answers questions.
Q. And then the accused falling back?
A. Backwards, yeah.
Q. Backwards. Did you observe him hit his head or strike any part of his body?
A. No I didn’t.

And below how this evidence was accurately reported in newspapers.

Leslie Andrew, a police constable who was one of the first three officers to enter the house after the 111 call from Bain, said he stayed with Bain as the two other officers checked the house.

He watched Bain from the doorway of his bedroom and when a dog barked from down the hall, Bain called: "Here Casey, Casey, Casey." When the other officers shouted that they had found five bodies, he saw Bain shaking for about 10 seconds and then falling backwards.

He noticed Bain's eyes were normal before he fell back, which he thought was "a bit strange".

"If he was having a fit his eyes would react as well," Andrew said.

He had seen people have fits before and had noticed their eyes would flicker and the whites of the eyes become prominent.

Andrew said he had pulled Bain out from the tight spot where he had fallen and placed him in a recovery position.

Bain, who looked straight at him as he pulled him out, did not hit his head or any part of his body and was limp.

Earlier, the police officer who saw David Bain have the fit that morning, Constable Leslie Andrew, said the episode seemed "strange''.
 
Andrew said Bain was sitting on his bedroom floor and then began shaking for 10 to 12 seconds before he fell backwards in a fit the Crown says was fake.
 
Andrew had observed other people have fits and their eyes normally changed and the whites became prominent before an attack.
 
Bain's eyes did not change before the fit and his episode seemed "strange'', he said.
 
Bain did not strike his head in the fit and when he went to assist David his eyes were open and he was "looking straight at me'', he said.
 
Andrew dragged a limp Bain into the recovery position and an ambulance officer was called.

As you can see Joe Karams version of what was said, completely contradicts what Constable Leslie Andrew actually said when questioned at the Bain trial in 2009 and as reported by both Martin Van Beynen and Ian Steward for Christchurch's daily newspaper.
