Rape trials without jury been argued for in Scotland.

An article on the BBC reports that at a Criminal Justice Meeting in Scotland law chiefs discussed the prospect of trial by judges for rape cases in Scotland. The article can be viewed from the link.

Without any doubt the protections provided by trial by jury would be lost. Any decision by 1 or even 3 judges with their own biases and potential political motivations and leanings are going to create far more miscarriages of justices than any jury trial.
Whilst juries may not be perfect they are biggest protection against sending some innocent people to prison.
