The problem with the law now is that the definition of self defence has changed since the Criminal Law Act 1967. I think the 1967 act was a safe way to determine if a person acted in self defence.
Since 2008 and the Criminal Justices and Immigratin act in particular section 76(4) which has incorporated case law it has become almost imposible to convict were the defence of self defence is put forward.
Providing one has a good QC it is very difficult to convict.
Both Steve Gerrard (football player) and Steven Terry (football player) successfully used the defence of self defence after battering people.

Ben stokes can now be added to that list.
Just some general enlightenment not necessary exactly correct (preamble before it begins phew!)
The law regarding self defence was changed due to some cases of wife beating.
In the past some women were abused and frightened to such an extent that they killed their husbands whilst asleep in bed.Using a hammer in one case IIRC.
They were subseqently jailed for at least manslaughter if not murder.
After years of fighting, appeals against the convictions were heard and the senior courts ruled that such was the control and fear of these women that they acted in self defence in killing thier husbands as they slept.
The courts said even though the women could have taken other measures that may have been plain to others to stop the abuse, as long as they honestly believed that what the did was their only course of action in self defence then they had a defence.
The distinction is that previous to these rulings it was for the jury/magistrates to decide if what was done in self defence was necassary. The jury/ Magistrates are now only required to assertain if the person held the honesly held belief that they were acting in self defence when they acted.Even if that belief is wrong. The judge must tell that to the jury.
That is a far more difficult thing to disprove.
At least section section 76(4) is a problem in attempting to convict if not ammendments to the entire act.

Some additional information.
I sat in on the Lee Bowyer(footballer) Grievous Bodily Harm trail. Lee Bowyer was represented by QC Desmond de Silva
https://www.independent.co.uk/news/...llers-charles-taylor-war-crimes-a8398896.html
There were two other people in the dock with Lee Bowyer.
In total there where 21 legal representatives solicitors and QC's with juniors most of whom were to defend those 3 people. Some of the seats were used in the public gallery for the legal team.
Oh I nearly forgot as if you did not know anyway. Lee Bowyer not guilty.
