Sure, but your argument seems too extreme. I would think the positives outweigh the negatives.False positive waste more than a phone line. If nobody responds, emergency services attend the location. It doesn’t matter when those 100 false positive occur. Every one carries a risk of killing multiple people through misdirected resources.
As it is, I'm sure the emergency call centers are getting prank calls now and also gets calls for minor incidents.
Not sure if you're looking for perfection tho., coz it'll be quite impossible to achieve.
