Justice on Trial

The Guardian has just begun a campaign called Justice on Trial, aiming to highlight cases where there is a major concern that a miscarriage of justice has taken place. (Pictured here is Sally Clark, who was wrongly convicted of shaking her two baby sons to death on the basis of now discredited medical evidence).

Miscarriages of justice do not appear to have gone away, as the recent case of the Cardiff Three shows.

There's a good short film to watch (but be warned - it contains some strong language from the start) and a fantastic slideshow of some of the higher-profile miscarriages of justice that have taken place over the years.
