People are actually angry over this? If you are sleeping put your phone on silent or do not disturb. If you aren't how inconvenient is one text message?
It only woke me up, but I wondered how smart they were. I mean, someone driving might have been shocked into an accident. The cost-benefit of a really loud system might be more cost.
If you're gonna send out an alert as disturbing as that one, at least include some relevant information.
The frustrating part is the lack of contextual info in the alert message. Mine said something about a car and its color, but nothing about the abducted child, area where he/she went missing from, etc.. It simply wasn't enough info to be useful to anyone.
This is a great way to destroy the credibility of our emergency alert system.
That sounds like the real issue here then. I'm sure there are others like you who found it useless but quite a lot of people who think it's a great idea. They need to offer a few on/of switches in the settings for types of alert (weather, terrorism, amber alert etc.).
