I dont think so KT.
Once Lorraine Smith raised sufficient doubt as to whether or not King did it and not Kahui, there was pretty much only one way the case was going. Police appear quite happy that he did it and have no plans to mount a further investigation.
From that I infer that there is plenty of inadmissible evidence that implicates him.
I'm saddened for Agnes Nicholas, but the case revolved around a witness that appeared a year after the event, recalling admissions from Foreman and being believed by the jury. For whatever reason, they chose not to believe her and the case fell, as it must.
The other one escapes me for the moment.
Really, its what can happen under our system. Its a great disappointment to the teams of cops that work tirelessly assembling the case and its a great disappointment to those deprived of a father/husband.
Still, better 10 guilty persons go free than one innocent man be convicted - or so the Law Lords would have us believe
