I knew there was more to it (though I can’t find decent coverage of the evidence.
I’ll settle for Garry’s account.
The reduction to manslaughter was due to ‘diminished responsibility’, the courts view of the crime was a million miles away from Max Clifford’s ‘self defence’
And there was much more to it than that.
I said that he was in illegal possession of a S.1. Shotgun. He had previously held a S.2. (ordinary) shotgun certificate, but this had been revoked about 5 years earlier, when he used it in similar cirumstances. He then aquired a 5-shot Winchester pump action shotgun, illegally, which requires a S.1., and that's the one that he used. From memory, I think that he claimed that he had found it on the farm, but that isn't easy to believe, not that it would have justified his possession of it, even if true.
Certainly, there was evidence of "diminished responsibility" but for some reason his QC ignored this, in other words there is evidence that he was very badly represented. I think that the public outrage led to the (effective) reduction to "Manslaughter by reason of". In addition, there was incorrect police evidence in that the lack of shot spread indicated (but only to them) that he had fired at "point blank" range. There is no such thing as point blank range with a shotgun, but we assume that they meant from a very close distance. In fact, with the choke fitted to his gun there would have been zero shot spread at a distance of less than 5 yards, which made his account that he fired from the top of the stairs much more believable. The police make this type of statement all the time, they should hire real expert witnesses in these cases.
There was a lot of public support for him at the time, he wasn't really a farmer, he was a merchant seaman who had inherited the farm, which was derelict. He was single, lived in very poor circumstances and had nobody in his life except his sister, he had been burgled many times previously and it seems that the police never attended when he rang 999, so he got a bit p***ed off and decided to take the law into his own hands. Unfortunately, this is exactly what happens in rural areas, even if the police try, and even if they can actually find the place, response times can be very long.
Since being released from prison he has again claimed to have a firearm (he can never again have any firearm, including an airgun, legally as he is now a prohibited person by virtue of having been sentenced to a term of imprisonment of 3 years or more) and the police carried out a search but found nothing.
