You are correct in the UK you are "presumed guilty until proven innocent" That is opposite of the US system..Maybe one is better than the other--but who is to decide that? Someone with a much higher pay grade than us.
No no, Tiger. Innocent until proved guilty. I think you got the idea from us, historically. In Scotland, which has it's own legal system, the jury has the option of a third verdict - "Not Proven" which falls between guilt and innocence but still results in the aquittal of the defendant. Actually, the choice for the jury in England and Wales is not Guilt or lnnocence, it's Guilty or Not Guilty, a subtle difference.
One big difference between our systems (UK/US) is that judges are not elected, but appointed, so they don't have to pander to the electorate. Though they can be subjected to ridicule in the press if they make a spectacular bad decision, and there is a mechanism for removing bad judges.
