Why is this coming up only now? Amber Alerts and various other fringe alerts have all the same issues as a general warning about a violent criminal.
What I really hate is when the weather alert system is abused to communicate other information. Weather is relevant to my life. All these other alerts are irrelevant to me because the probability of a homebody in a big city spotting a person or car based on a generic description is exceedingly low. I should be able to elect to receive only alerts I am interested in.
