Myth can be made redundant and reliable. TV distribution systems can not.

I recall when they installed tornado sirens around here. The first tornado 
immediately took out the power lines used to power the sirens, followed 
closely by the telephone lines used to turn them on. Needless to say nobody 
got any warning from the sirens.

Should they have been battery-powered and controlled by radio? Of course, but 
politicians were involved, so...
