When I was teaching, an Amber Alert set off a bunch (23-27 phones) of my HS students’ phones. My kids wondered why my alert didn’t go off. I told them that I have them turned off because I teach. They thought I was thoughtless until I pointed out that I was sure that we wouldn’t spot the missing child from inside our classroom.
I have them turned off, but a “Silver Alert” (for missing elderly people) came through on my CA-based cell phone sometime in the last two weeks. Not sure how the local authorities get permission to override this with the carriers, especially since the alert was over a week old.
