If you found yourself in court, on trial for a crime you had nothing to do with, would you plead guilty or innocent to the false charges brought against you?
Certainly you would plead innocent! It would be absurd to plead guilty to a crime you did not commit and then have to suffer the attendant penalty.
Stop and think though—how often have you done just this; pleaded guilty to completely baseless charges against you and then suffered for it?
