Thinking about the Letby case more, wouldn't it make sense on certain wards to have 24h security cameras rolling? If people are doing their job properly there will be no concern. But if there was some sort of major issue like what happened in the letby hospital it would be used with notes to put together a picture of what happened. Children's wards and neonatal wards should have cameras on the beds/cots all the time.
I'm not looking to blame people for minor mishaps but more to get to the bottom of potentially "life ruining" events.
I think the same for schools. It would protect teachers mainly. There would be no word of a student against a teachers. Schools have become increasingly violent.
