The reality of working in law enforcement is that you dismiss an emergency call at your own peril.
Regardless of how absurd, questionable or repetitious a call may be, if something horrific occurs and you didn’t respond, your ass is grass.
And that’s just the way it is.
It’s not that it’s just their ass. It is that they don’t want her murdered or attacked. If someone wanted to attack her, it would be kinda nice to put out some false alarms.
They should not stop responding, but the NSA and CIA have the technical ability to find the terrorist. And they have the legal ability to pursue a terrorist attack.
The bad thing is not that cops take each call seriously, it is that our government does not want to stop the attacks.
