FWIW: In Sweden, there's been a bunch of cases of emergency personnel being attacked when responding to incidents

I understand, I know it's a problem in France too, even in hospitals. Or Firefighters being called only to be attacked...

However that exists already, without a way to track the rescue team sent to you...

if someone wants to attack them they can call them. so what's the point of not providing this very useful information to the public?
