Indeed.
Indeed. This is how it is supposed to work in all civilized countries with the rule of law. When a case is made up entirely of circumstantial evidence (which many are), the trier of fact is to assess each piece of circumstantial evidence for reliability and evidentiary value, if any, as against the accused. This is not even remotely close to requiring proof BARD with respect to each piece of evidence, as some PGP suggest. It is simply that they do not wish to understand the proper process for assessing pieces of evidence.
If any given piece of circumstantial evidence is unreliable or has no evidentiary value against the accused, then it should not be considered further when it ultimately comes time for the trier to fact to assess whether or not the totality of the pieces of reliable and probative evidence as a whole amount to proof BARD.
Hellmann nailed this, and his written judgment is the only one released yet in this case that passes juridical muster and demonstrates a proper appreciation of the law.
Moreover, circumstantial evidence is sufficient to warrant a conviction only when it is consistent with the conclusion that the criminal act was committed by the accused AND that the facts are such as to be inconsistent with any other rational conclusion other than that the accused in the guilty party. That is to say, the test for conviction based on circumstantial evidence is that the trier of fact must be satisfied BARD that the only rational inference that can be drawn by the circumstantial evidence is that the accused is guilty.
This has been the law for a long, long time here in Canada, and it is supposed to be law in Italy as well. The elements of an offence have to be established BARD, and while an element of an offence can be based on circumstantial evidence, that is only so when a trier of fact is satisfied BARD that the guilt of the accused is the only reasonable inference to be drawn from the proven facts. The proven facts are those that have survived scrutiny in the initial assessment of the evidence (for reliability and evidentiary value, etc., as noted above). Reliance on irrational or speculative evidence to support an inference of guilt is not appropriate, and cannot properly sustain a conviction.
It is reassuring to see that this is the process of judicial assessment followed in Canada. We use a different model in New Zealand. It is deemed unacceptable to not prosecute someone, so the police charge someone who has a connection to the victim, and fabricate evidence, and fool the people, the judges the juries and the politicians into believing their game each time.
Wrongfully, prosecuted at the very least are
Walter James Bolton, Hanged for the murder of his wife. Innocent and the murder was probably committed by his sister in law if it was murder at all.
Arthur Allan Thomas. Jailed for nine years for a double murder and exonerated.
David Tamihere Jailed for twenty years, still considered legally guilty, for a double murder committed by another man
Teina Pora Jailed for 22 years and exonerated
Scott Watson Jailed for 17 years, eligible for parole in june, which will be denied because he will refuse to express remorse for a double disappearance engineered by other parties.
Ewan MacDonald Miraculously acquitted for a murder committed by a gang. Many New Zealanders and the victim's wife remain convinced he is the killer.
Mark Lundy Jailed for 13 years, released for one year retried, convicted and jailed for a further 7 years. Parole will be denied because he will express no remorse for the murder of his wife and child committed by others.
Only in the case of Teina Pora is the known killer of the victim in jail.
In all others the killers are allowed to roam free if they are alive or not in jail, and the police have ceased investigating.
Of course they all represent gross violations of every principle LashL describes above. There is no reason to consider any of the above more guilty than Amanda Knox, and I have no doubt at all they would all have been acquitted by Hellmann, and indeed by those fine South African judges who understood the Pistorius and Dewani hoaxes.
