I read the story and there is a lack of detail. There are no accounts of what she does that make ths action necessary.
I could see an occasion when it might be apparent to all that a disaster with a newborn was in the works unless action was taken. But this account doesn’t make any case for that.
It is not what she has done, it is what was done to her in the past.
Miss Lyon came under scrutiny because she had a mental health problem when she was 16 after being physically and emotionally abused by her father and raped by a stranger.
