What’s her behaviour as a whole?
If you bother to read the live updates from Court you’ll find her behaviour as a whole.
I’m also curious as to how you account for the other factors: that statistically, it’s far more likely the deaths can be attributed to natural causes
There were at least 8 senior medical witnesses - from paediatricians to endocrinologists to pathologists - who proved the deaths were not as a result of natural causes. Again if you read the live updates from court you’ll find the answer to your curiosity
That the unit was under-resourced (and this had been raised by senior doctors)
Letby was given opportunity at the start of every day, during her testimony, to change her mind as to the account she had given on her police statement. She, herself, stated, several times, that the unit was not under resourced.
The unit was downgraded (if it had no fault why would this be)
The unit was downgraded after Letby was arrested. There has been no explanation why it was downgraded. Your guess is as good as anyone else’s.
