I have asked this elsewhere but was there a warning that was going to happen? For women with secret phones ( domestic abuse) it can be quite dangerous.
There were warnings preceding the tests when the system was originally set up (there have been two tests), but they can't send a warning about an actual alert. The alerts come as and when are required, sometimes at very short notice.
As for those with suffering from domestic abuse who have secret phones, the alerts can be turned off so that they are not received by the phone. Obviously the people concerned wouldn't receive any alerts, but I would imagine an alert would be of less importance than their personal safety. It's just unacceptable that people are treated so badly that they have to make that choice.
