This doesn't sound like the BBC, no matter if they pay or don't pay some participants.
Take a look on the article, for instance. It says that Martin, who - on his own property and having not police protection - releived the earth from a lowlife during an attempt to rob him, was jailed for murder reduced on appeal to manslaughter.
But it doesn't say for how long...
However, it says that the other burglar got 6 months (!).
Surely the victim of the crime had received longer sentence than the perpetrator. And it is not mentioned in the article for the purpose of good balance, I suppose.
Actually, Tony Martin was in prison for much longer, had to pay the perp for shooting him, as well as going through all the frustration of being the 'bad guy' in all of this. His house had been broken into around 24 times when he'd had enough. He got into trouble because he had an 'illegal' shotgun and because the guy that died had been shot in the back. He was running away. I think it stinks, the cops said he should have let them go; but if it'd been me, I'd have done the same. How would Mr. Martin know they weren't going for guns or knives intending to come back!
