You may not wish to think about it, but one day you or someone you love will almost certainly appear in a criminal courtroom. You might be a juror, a victim, a witness or - perhaps through no fault of your own - a defendant. Whatever your role, you'd expect a fair trial. I'm a barrister. I work in the criminal justice system, and every day I see how fairness is not guaranteed. Too often the system fails those it is meant to protect. The innocent are wronged and the guilty allowed to walk free. I want to share some stories from my daily life to show you how the system is broken, who broke it and why we should start caring before it's too late.
