to me it's not so much intrusions but fire safety - I want a way to call 9-1-1 in the middle of the night if my smoke alarms go off
If I (bizarrely) got a message informing me that a tornado was about to hit my house, I'd a) assume it was a scam b) have no idea about what I was supposed to do about it anyway. Hold on to something solid to avoid getting sucked away?
