And, this week, the story of a man, "Michael Smith", which is not his real name, who was jailed for 14-and-a-half months for abusing one of his two young sons. He was innocent, too. He is on good terms with the boy, whose name is also changed, now grown up, whose "evidence" helped convict him.
"Michael Smith" seems a decent man, capable of forgiveness - two of his siblings believed him to be guilty; he has since resumed a relationship with them, too. He received compensation - long gone; he developed a gambling addiction.
The then-teenage girls also got compensation, also long gone. The mother of one of the girls said, sadly, she had no idea what her daughter had done with the money.
"Michael Smith" also received an apology from the police but, as he said, nobody had ever apologised to his son, who was still crippled with guilt about his false accusation.
These are not stories with happy endings.
They are of lives that went off the rails after the wrongly accused were found to be innocent. Prison does bad things to to people; whispers don't stop; entire families - and their finances - are shattered.
"Michael Smith's" story was almost unbearable. His sons were being abused, by their stepfather. He became bitter and angry, said his lawyer, Rob Harrison - who must be a sort of hero - who believed in him and has never judged him, even when he became unpleasant to be around.
"Michael" had planned to use the compensation money to in turn compensate his parents, who spent all of their retirement money and re-mortgaged their house to help get him out of prison.
They died before he got the money. It felt like "blood money", he said, so he got rid of it.
This was a terrific feat of documentary making. Everything had to be reconstructed and so dramatised, which all too often means over-dramatised. I Am Innocent tells its stories calmly and methodically - using the words of those who are the real victims here.
But methodically does not mean ploddingly. These are stories with a compelling narrative drive and they are told with authentic compassion, never overdone.
