Ben Gunn.

Watched Michael Portillo programme last night about the now closed prison at Shepton Mallet.
It featured one Ben Gunn, murderer, who had been incarcerated there.
He was imprisoned for killing his friend by 'hitting him with a piece of wood'. He claimed no intention to kill. Odd - as that is clearly manslaughter.
I looked him upon Wikipedia and found a rather different tale: what had clearly sounded like a single blow was actually a multitude of blows.
Big difference, innit? Why did the producers of the show allow this very different impression to be given, I wonder?
