There is enormous pressure on people to plead guilty in return for concessions, and the whole legal profession knows that if a significant percentage of the innocent do not plead guilty the system would grind to a halt.
Another aspect of our justice system that requires urgent reform. People should not have to sacrifice their good name to try and avoid prison. They (we) are entitled to a fair trial without being put under such monstrous pressure.
