Jack, read my words:
In UK at least, there is a presumption of innocence, which continues until such time as a guilty verdict has been achieved.
Despite the differences between judicial systems in England/Wales and Scotland they all agree on their being a "Presumption of innocence"
In the Scots system that presumption continues if there is no guilty verdict even if there are two different "not guilty" verdicts ("Not Guilty" & "Not proven"). This "Presumption of innocence" is the matter I referred to when I used the term UK.
