There is plenty of room to debate tradeoffs in patient care. However, the policy was to perform a check every 15 minutes overnight. Not great for sleep quality and, all else being equal, a net negative for mental health. However, it does prevent a long tail of serious negative outcomes (such as, potentially, this death). There are a bunch of healthcare circumstances where sleep quality is sacrificed in favor of other concerns.
In this particular case, in addition to all of the normal concerns the facility would have, this girl was:
- on a new medication
- nauseous
- unwell enough that she cut a phone call short to go to bed early (which sounds like was out of character for her)
Those are all red flags that her condition should be monitored closet than normal.
The entire logic of the Court's opinion rests on the fact that bump stocks still use a seperate trigger action per shot. They just cause the trigger to automatically trigger against a stationary finger instead of the shooter needing to manually actuate their trigger finger.
Is this an obtusely litteral reading of a law that was clearly intended to be more broadly interpreted? Probably. But it is a reading with a majority support on the court, so we are stuck with it until congress amends the law.
