I absolutely love this programme
If you haven't seen it already, I would really recommend Reasonable Doubt - five seasons of that. Lots of (mainly) very delusional families trying to get convictions overturned.
There were some successes though and people have since been released but not necessarily as a result of the show. I'm still following one case that's due for a retrial in September. Season 2, episode 1 - Convicted by a Hair if you're interested.
It was actually one of my favourite USA crime shows, despite it clearly being very scripted and the general overacting of Chris Anderson, who was also a detective on The First 48. I was sad it got cancelled.
Oh and definitely Accused: Guilty or Innocent? There's seven seasons on that. And it's spin off Accused: Did I Do It? There's a season of that.
All available on catch up.
