Which is what he is doing.
I’m wondering if he doesn’t really know how his tv works. Also, maybe he has PTSD, thus the tizzy over the loud noise (mostly kidding; no offense intended to PTSD sufferers).
As someone whose family made it to the basement thanks to the alerts, I’m pretty darned fond of the tornado warnings.
You’re literally complaining about kidnapping**. What other crimes involve immediate danger to innocent civilians not in the immediate area? Another mass shooting somewhere? The best thing is for you to stay away. However, a child has many less smarts & strength (due to age) to get away, if they even realize that they shouldn’t be with the non-custodial parent who took them somewhere.
While I agree that TV might not be the best way to disseminate an Amber Alert due to the fact that people are in their homes & not out & about where they might see the target vehicle if they weren’t so loud they wouldn’t get people’s attention. There’s many a time where I’ll get up while watching some sporting event to tend to food; whether that’s pulling something out of the oven, refilling the pretzels/chip bowl, or getting another drink. If I hear the announcers go crazy I run back in & can frequently catch the end of the play that they were getting so excited about. I’d totally miss anything that was just a crawler across the screen,
However, there is a very simple solution for you, try turning off your TV some time; the horrors of having to enter a channel # again.
There’s a setting on many TVs now that allows the set to be controlled by an external device – for instance, docking your Nintendo Switch when it’s on would automatically turn on the TV. Is it possible that something similar is happening with the OP’s cable box and TV?
