(Hat tip to peteretep for the updated figure).
At least 5-10% of people get off on technical details the police or prosecutors messed up or just good lawyering of guilty people. The rest the cases fall apart before trial because of witnesses or other evidence and turns of events. (I’m pulling these numbers out of my ass just to make a point).
The problems in Japan are with the due process and a serious lack of rights of the accused. Even if we completely ignore the conviction rates.
In the UK, the CPS only prosecute cases with “a reasonable chance of conviction”, which I guess means they essentially choose the conviction rate they’re aiming for?
We saw how that works in practice recently with that FBI report where the judges were basically yes men trusting everything the FBI told them without even basic scrutiny...
The Japanese system is more on the input end regarding due process and rights to counsel.
It is therefore expected that conviction rates should be relatively high whether in the UK or Japan.
However, 99% really looks like rubber stamping a decision that was already made by the police... and that's a red flag.
