I don’t like these. For one thing, I don’t think it’s an appropriate use of the public attention to draw attention to random crimes you want to solve. You’re casting too wide a net for too small a target. Of course people are going to defend it because of our “think of the children!!!” emotional reaction but you’re just sort of training people to tune out of emergency alerts for minor things that almost certainly won’t affect them. I know I ignore the emergency alert messages on my phone because it’s probably just going to be the license plate of some dude that kidnapped his kid from his wife during a family dispute. What if it was an alert about a chemical leak or something that I really needed to know about quickly? I may well not bother to look because it’s used too often for things that affect almost no one.
Secondly, I don’t think it’s psychologically healthy to remind people of crimes happening in a broad area around them. This isn’t specific to emergency alerts but applies to crime/tragedy focused news in general, but at least with that news you can choose not to watch it, the mobile phone alerts go to everyone. Our society is already hysterical at the idea that danger lurks around every corner and you can’t let your kids out of your sight for one second because there’s a hoard of school shooters and child molesters around every corner!!! This is not mentally healthy.
We live in a great, safe, peaceful, prosperous time to be alive (especially if you ignore the last few years specifically) but everyone is miserable because they’re convinced that the world is falling apart and it’s the end times because the media sells them fear. Everything is terrible! Crime is everywhere! Tragedies are everywhere! Terrorism is everywhere! But it’s not true. People are convinced it’s more dangerous now than it’s ever been, but it’s almost exactly the opposite. But people can’t understand how big their region/country/world is, they don’t understand that with millions of people around them, hundreds of millions in their country, and billions in the world, if you hear about every bad thing that happens you’re going to be completely swamped by those bad things even if they’re rare and the world is generally safe. To most people, the world feels like a few hundred, or maybe a few thousand people deep. That’s how they conceptualize it. Their brain can’t handle the enormity of the real size and numbers. So when you tell them 20 bad things are happening today among hundreds of millions of people, it feels like it’s happening among the hundreds or thousands of people they perceive the world to be, it’s like they live in an isolated village where dozens of people are having bad things happen to them every day. That’s what gives them this distorted sense of danger. They’re getting the bad news from 7 billion people, and it feels like it’s happening to their little village to them.
Anyway, having constant CHILD IS IN DANGER! CHILD IS KIDNAPPED! messages only reinforces this perception and hurts their psychological wellbeing, and makes them influence/vote for policies that are wrong based they’re based on false premises, that actually damage the world more than the events they’re trying to prevent.
For related reasons, I oppose running “active shooter” drills or re-designing schools in obvious ways to mitigate school shooters. Yes, someone shoots up a school once in a while, but there are 125,000 schools in the US. The odds of your kid ever being in danger are extremely slim. And yet our obsession with focusing on every school shooting, and running active shooter drills, and all that, are scaring our kids to death. They’re convinced they’re not in a safe environment and it hampers their learning and their psychological well being, even though shootings are rare and statistical fluke and extremely unlikely to affect them. But the active shooter drills and perception that they’re constantly in danger is going to affect them. Inflicting that on them does more damage than any active shooter drills would mitigate.
