I turned amber alerts off on my phone after multiple alerts at 2am for someone over 100 miles away.

Are you sure about that?

Isn't that the thing that wakes me up at 4 AM when I forget to disable it on a new phone? No, I don't think it's a good idea.

Good idea, less than great implementation. But still, it's just a presumption--presumptions can be overcome.
