Let's start with our wonderful criminal justice system.
A chap beats his lover to death when she decides not to leave her husband for him.
Manslaughter, obviously. No reasonable person could have supposed that smacking a woman round the head with a wooden mallet was likely to kill her, could they now ?
2001. A mighty seven years for this 26 year old. Let all evil-doers tremble.
"He was released on licence from his seven-year sentence in October 2004."
Let's move on to a the Carter family - the British one. Mum has a daughter of 16 - or maybe 15. I'm not sure I'd want my young daughter to be 'seeing' someone of 31 - let alone a guy with a track record like that.
Ah well. Pity about the kids. The little girl's freckled nose and clear gaze remind me of my darling. Poor child. How could anyone ?
On the evening of March 9 he allegedly rode his motorbike from his mother's bedsit in Leek where he was staying to nearby Cheddleton with a holdall containing at least one can of petrol, a tealight and a cigarette lighter.
The trial at Stafford Crown Court was told that Goldstraw probably let himself in at about 11.30pm, spread petrol around the hallway and set the fire.
The resulting petrol vapour explosion woke the neighbours, one of whom heard Marcus's chilling screams through their shared wall, and some rushed outside to see his sister Patricia trapped in the front bedroom.
But the intensity of the blaze that followed meant no-one could be saved - fire officers said it was the worst they had ever seen.
Meanwhile Goldstraw is alleged to have run from the scene to the pub where he had concealed his motorbike, ridden back to the home of his mother, Lucia, and taken a shower.
He was arrested the following morning but refused to comment on his whereabouts the previous evening.
Police found his fleece, jeans and trainers in a wheelie-bin outside his mother's home, Mr Hotten said. They smelt strongly of petrol and bore scorch marks.
A teddy bear, necklace, pair of earrings and watch identified by Mrs Carter as belonging to Samantha were found in his leather jacket, he added.
And a holdall found discarded close to the scene of the fire contained petrol residues and fibres matching Goldstraw's fleece.
In addition, the jury were told that a witness who saw a man running from the blaze had identified him as Goldstraw.
Mr Hotten said Goldstraw had been convicted of manslaughter in 2001 for battering his lover Deborah Wheatley to death with a mallet after she said she would not leave her husband for him.
He was released on licence from his seven-year sentence in October 2004.
While this might be "an unfortunate coincidence", he said, it could explain "why this man, of all men, would react with murderous violence when others would not have done".
Goldstraw is charged with four counts of murder, all of which he denies. He later claimed he was riding his bike around Leek at the time of the fire.
