I didn't follow the trial at all. I did listen to some of the interviews with the doctors afterwards, they had no doubt on their mind about her guilt.
They painted her as the 'scarlet woman', killing babies to get attention from a male senior colleague. They were also very upset they had to apologise to her following a grievance. But, they were totally convinced about this, and in turn convincing. On there testimony, I thought she was guilty.
There is the concept of group think, where a group of people reach a decision without critical evaluation. Just because a group of doctors came to a conclusion, which they passionately believed, it doesn't mean that the conclusion is right.
And 'expert witnesses' have caused miscarriages of justice before.
