OK. I know she's an idiot.
But is she wrong? In practical terms:
Does "law enforcement" have any liability for failing to prevent crimes? Aside from certain politicians, does "law enforcement" have any obligation to protect anybody? What penalties, if any, does "law enforcement" face if it fails to intervene in an ongoing crime?
What does the Supreme Court say about this?
The Supreme Court ruled your municipality has no obligation to you, whatsoever.
