I'm under no legal obligation to do my job either. Doesn't mean I won't face discipline if I stop working. The job of police is to protect and serve. That's what they're trained to do. Whether or not they can face legal consequences if they refuse isn't really relevant here.

Your job likely isn't backed by the state's "monopoly on violence", either.

You - and others - keep missing the part where I said "trained" rather than "legally required".

That means they can't be sued for this, but GP is taking about their training, and departmental policy/procedures. It is their professional responsibility to stop the threat.
