Whilst I certainly sympathise with such a view (given the reputation of US police officers right now) often they are the first responders to dangerous scenarios. As such they are required by their job to make medical split second decisions by default.
And like it or not, that includes instances where a person is so mentally ill, they need to be, for lack of a better phrase, locked up for their own good.
A first responder needs to be able to make that call. If it’s the wrong call, then sure, the person should absolutely have the right to challenge that in a court of law and ideally that should not be at cost to them. Though in the US going to get a doctors note costs you guys more than it does me, so again I can sympathise with the view that this unfairly targets the poor. Given that obvious lack of options in such scenarios
But I mean, I just don’t see this as authoritarian, I’m sorry. It’s just a required safety net that sometimes citizens need.
But I would agree that it’s perhaps far better for a doctor to make that call. Though given the US costs of medicine, that’s perhaps unfeasible. So this is just NY working with what it can, as far as I can tell
