That is as stupid as advocating gun control. You get a warning to go to high ground, in a place that does not have cell phones, or cell coverage, but is in the dead of night when nobody is awake to hear it and there is no high ground because it is in flat Texas.
Hurricane and tornado warning happen, yet hundreds die anyway.
We cannot control the weather (fires, earthquakes, etc…) but we can control infrastructure and preparation for “what if” scenarios. There’s a reason why an earthquake in Japan kills less people than a 3rd world country without building codes hit by one of the same magnitude.
